The problem is I have other snails I want to keep in the tank (which the limpets compete against), and generally these formulations contain copper which will also kill shrimp and embed itself in your silicone preventing keeping any invertebrates in that tank in the future.

Yeah well, there was a time I liked them too. But then they blanketed my front glass and didn't go away. Any case, they compete with my Theodoxus Fluviatilis snails - so glad for them to be gone. They came into my tank on some Elodia Densa from a long-time LFS I put into another tank, and when I...

I had a tank with freshwater limpets - Acroloxus Lacustris and they were obscuring the glass on my 37 gallon tank and didn't 'naturally go away' with time - had them for 2 years! Really bothered me in fact. No one seemed to know how to get rid of them, but I recently added a juvenile angelfish...

I gave my friend some Theodoxus nerites and he had a hidden assassin snail in his tank, and yes I saw it eating one it must have killed. Though theos are smaller than the normal nerites.

Cool. Morphologically they look like Crystals.

So cool. Why do you think your colony died off without replenishing?

What is a circulator? You just mean a filter?

Just curious what shrimps everyone is keeping in the UK besides Cherries and Crystals. Post here with your experiences and pics if you can :)

Get some Theodoxus if you like nerites but don't like their eggs. Win win.

If you get moss from an established tank it will have some. That's probably your best bet. Try the forum for some moss out of a member's tank.

Looks to be a type of nerite. More than that I can't say as I have never seen one with a shell like that before for sale. Where did you get it?

Theodoxus Fluviatilis nerite eggs rapidly disappear and do not mess up scapes. These are the ones that successfully breed in freshwater. I would get those.

I'll just post this here for posterity. I spent several years trialling Theodoxus Fluviatilis shipments from Germany until I finally cracked the Theo code. Here are the rules for success. 1. There must be ample 'smearing' algae in the tank OR your tank must get some direct sunlight (which is...

Well, I still have them and they are breeding well, but I moved back to the USA so can't supply them to y'all beautiful UK peeps anymore 😐. Best snail ever. Some other members still have them here. Hopefully they will redistribute 😁

Orange tylos also eat my marsilea - so in short they LOVE ferns.

My betta ate rcs size shrimp indiscriminately and terrorised a full grown amano into constant hiding / jumping if you put them together - it constantly tried to hunt and kill it even though it can't swallow it whole.

I am pretty sure now that indeed the heat killed the babaulti's and my Hyallela. This makes the most sense. It got hot last year (30C+), but not as hot for so long (2 solid weeks this year). Oh well, try again. Thought this wasn't a problem for tropical shrimp. I ordered some green babaulti's on...

Embers do not view babaulti shrimp or gammarus as food. Also I have never seen Embers even peck at the decor - let alone a possible baby shrimp invisible to the eye.

Found this article. It says that Hyallela azteca die at a water temp of 33C for 11 hours. This is a little higher than any temp I saw, but not out of the ballpark. https://www.journals.uchicago.edu/doi/abs/10.2307/1538194?journalCode=bbl

As I recall they were sold to be as the smaller mexican Hyalella azteca. I really don't see any more of these in the tank - which is weird because I had so many there were on the glass. I keep about 12 Corydoras Habrosus (they breed in my tank) - which can take air from the surface, and 4 Ember...

Upon reflection it doesn't make sense that the heat killed them. As my tank didn't get THAT hot. The reason I feel fairly confident about saying this is that my tank has had gammarus for a little over a year, but they now also appear to have been all killed off...what? Nothing kills gammarus...

Interesting that this thread came back up. My shrimp decided to all go red about 6 months in. But the real reason I am revisiting this is that I just noticed that my aquarium seems sans shrimp. I think the heat may have killed them all. Never noticed their bodies. I just see now that they are...

If you want multi-coloured shrimp get babaulti - I have greens, reds, and yellows and they never mix and fade.

OK so I got the babaultis. They are definitely not a green shrimp. But green, red as a decent cherry, orange, yellow, one brown, a few weak coloured ones. They are a whole rainbow. It's like I have many species in one tank. I can also say that they are super flighty, and hide super well. But...

As Darrel says that snail is Tarebia Granifera. It stays smaller than Melanoides. I actually have a breeding population of black Tarebia Granifera I picked up in Switzerland - really beautiful. Happy to send you some if you PM me with your address. Cheers

And what happened? They didn't pay rent? o_O

Two years is decent. Did they die for no reason or a mistake? It would be cool to get some freshwater breeding red-noses. I don't know of anyone who has them. Is anyone going to Australia soon and wants to Han Solo it?

I am thinking about getting some of these shrimp and want to hear what you all have to say about them. Some claim they actually eat algae - the way amano and red-nose actually put their face down into it and eat. As opposed to cherries, tigers, and Caridina simoni simoni which in my experience...

Hopefully they will hold on until May, which is when they really breed like mad. The snail's shell looks healthy so fingers crossed.

A few years ago we had some discussions around red-nose shrimp and how basically they do not adapt to freshwater and all die inexplicably after 6 months max. Is this still the case? Has anyone kept them longer than this? I still like them and wonder if any of these issues have been solved by...

Ooo nice photo.

I have some. Tiny however - like bbs size. PM me.

So in the past I have tried to keep Theos in soft water, and what inevitably happened is that their shells would corrode and it seemed to me that the snails would begin to die off. As a result I upped the hardness. About a year ago however I did an experiment where I put some Theos from 10kh...

I tried keeping freshwater nerites (Theodoxus Fluviatilis) initially in ph 6.5-ish water, but the pitting in the shells from the acid water eventually kills them (takes a couple months). When I raised the Ph over 7 they stopped dying and started breeding.

my 2p http://www.lfkc.co.uk/index.php?topic=472.msg3619#msg3619

They are super pretty. Always wanted one - but have never seen them for sale anywhere - best bet might be german sites.

Tylos ate my java fern and coral pellia - ignored crypts, anubias and moss.

Awesome thanks Alastair!

Hiya - so I bought some Nannostomus unifasciatus today - and in my opinion one of them has 3 spots of ich on him - bought inadvertently. The tank they are in has plants and inverts (shrimp and snails). The recommended treatment (without medication) is to bring the tank up to 88F and then add...

FYI I have read that Asolene Spixi will eat hydra. Never tried it though...

If they are flat miniature ramshorn snails = Gyraulus sp. I have kept them loads and they are no trouble and I think look cool, especially when they twerk their bodies around. The pink rams I kept them with eventually out-competed them and they disappeared. Every tank could be different though.

I have killed shrimp before by putting them into a VERY high CO2 environment. As I was acclimatising them they stopped moving and picking up food with their feet. When I put them in the tank they all started pinging and dying in short order. Luckily if I caught them and put them in a tank with...

yeah. the quality of their bloodlines really shine through.

where did you acquire those shrimp from? incredible colours.

I use Tropica +NPK and without NPK and often overdose and have no problems with my shrimp (Caridina Simoni Simoni) or various snails.

smaller life forms are less susceptible to inbreeding problems. You will never have to worry about this being a problem for the health of your stock unless you are inbreeding for many many generations...ie like CRS.

Little updae. Interestingly the shrimp was fine carrying his carapace around for a week or so. Then he just appeared normal. So even though he had a hard time molting, still alive. Whew. Water was quite hard gh around 8.

Yeah I have to give a hat-tip to London Dragon. Panacured Tylomelanias, rams, MTS, and various shrimps, and never any issues. Sometimes it takes 2 doses, but the planaria always disappear for good and leave everything else unaffected. gotta love it.

Thanks for all the suggestions. Interestingly, the half molt eventually seem to slough off, and now the shrimp seems fine, but it took many many days. Really strange.

Ok so I have 2 pretty rare and expensive Macrobrachium Kulsiense, and one them has been trying to molt for over 36 hours, and is still half-in and half-out of its carapace (mostly in). It's face is covered by the carapace, and I am pretty sure it can't feed properly like this. I highly doubt...

Mark, you will sell them to the forums at some point won't you? Not only do I want them, but med-size shrimp that are peaceful and breed in freshwater are super rare, and there have to be quite a few hobbyists who would be interested. And if they eat algae like the amanos so much the better for...

Depends on the species. Melanoides grow to about 2.5cm, Tarebia about 2cm. We have some introduced MTS in Hawaii I collected in the wild and they grew to 6-7cm however. But in tanks they stay smaller.

Very easy to remove eggs, and they dont leave a mark when removed. They are just a soft gelatin-like substance.

I have these in my shrimp only tanks. I dont know what they are, but they are only about .5cm long. They sometimes like to swim by flicking their bodies back and forth, but the mostly crawl on the glass like a caterpillar. They are not planaria. Fish like to eat them though. Dont worry if you...

Well Mark, I must say those shrimp look like amanos to me. Whatever their identity, if your 'amanos' eat algae like real amanos, who needs a real amano...So, do they?

photo please ;)

Ph >7, Kh >5. Anything less and they wont like it. If you are little bit under they can tolerate it, but go more than a few decimal points and their shells will start to seriously corrode. I am having that problem on a tank at the moment with Ph 6.7 and Kh 3. I killed two nerites in there in...

In my experience nerties cannot be supplemented with any food but algae on hard surfaces, they just ignore it. If you dont have enough of that or if you water is too soft and acid they will wither away and die. Your nerites behaviour is worrying Sajit. Let us know how it goes though...

They grow slowly but steadily from what I remember. When they are really little they do seem to grow a bit faster though.

I used to keep Tylos for a while, and yep, what you got there is a little baby. Congrats :)

That's a cherry shrimp. Looks a bit like the 'blueberry' RCS shrimp they sell in the US, which can be anywhere from blue to black.

wow, all i did was make a suggestion. i didnt expect the fan-fish inquisition :twisted:

turn down the flow rate?

Caridina Simoni Simoni - kept it for 2 years now. Red-nose - lasted only 6 months :( You can see him here eating my BBA, and yes he wasn't just picking at it he did eat it. Good ol' boy he was.

I dont like the stocking method. The filter clogs in one day...Foam block is a good idea, or just use an internal filter. Eheim also makes a prefilter sponge if you are using their stuff. In any case, good luck.

Ramshorn is the best snail for algae. It eats BBA, algae on the glass, and just about everything else except spirogyra (if you find something that eats spirogyra let me know). It doesn't touch plants. MTS is also good at eating algae on the glass, but it wont touch BBA. These two snails are good...

another natural cure is asolene spixi which will eat hydra...and your plants.

ramshorn snails are the best snail to rid you of all sorts of algae. MTS will eat algae that ramshorns will except BBA. Nerites are the best snail to clean hard surfaces, but they wont eat anything but algae and can easily die of starvation and will leave eggs everywhere that cant hatch. Other...

for what it's worth, I kept Caridina Simoni Simoni in a ~2 liter bowl for four months during the summer and it survived and grew. However, when I returned it to a tank its colours greatly improved. Since I kept this female singly I do not know if she would have bred in the bowl. An interesting...

As a shameless plug, Caridina Simoni Simoni is very hardy and also breeds very well.

Mini-ramshorns (Gyraulus sp.)? I am pretty sure they are regular ramshorns (Planorbis sp.). If you want mini-rams I got some...

I was searching for the previous thread but I couldn't find it so I am writing it here. My red-nose which I had for 5 months died inexplicably. It grew a great deal and was very pretty but died for no apparent reason. a1matt had three that similarly disappeared for no apparent reason. So mr.luke...

Re: Vibrio harveyi bacteria cause death and shrimp glow in d I dont think it is really possible to treat shrimp for diseases they may have or be exposed to, as any chemicals you introduce risk upsetting them more. I would recommend trying to keep the tank as healthy as possible. Frequent small...

You cant look at shrimp and tell they are 'ready'. But if they are pinging around you know they are not ready, in fact, they are on the verge of death and you need to stop the acclimatization until they have stopped flicking themselves and swimming madly around. This is what 'pinging' means. In...

Depending on how different your new water is from the shrimp water, this acclimatization recommendation will kill your shrimp. For example, I have changed 1/2 of my water over one hour and killed 50% of my shrimp population as a result. If you want to be sure you do not kill your shrimp, the...

I can't tell for sure from what is online whether or not blue tigers will breed true or produce non-blues as well. Cheers for your experiences every1.

Like many of you, I want to bring a bag of shrimp back to the UK in my luggage to keep for myself. The shrimp will come from outside the EU while I am vacation. Does anyone know what documentation hurdles I will have to clear to do this legally? No cheeky responses that I can just "chance 'em"...

No, that's 8 Euros for cardinal shrimp. Which is a delicate and beautiful sulawesi species. Their prices are quite good overall in my estimation.

Hey Garuf, could you find the breeding post for us. Would love to check it out!

This guy begs to differ... http://ukshrimp.co.uk/forum/viewtopic.php?f=17&t=1328

I always thought it was a marketing ploy, but it really is true, and they do a good job. I got that soft fluffy algae on the glass in one of my tanks and I recently put some Melanoides Granifera in, and they are mowing right through it. Photography was difficult, but you can sort of see the...

I wouldn't dose any medication into a tank with CRS. If you think your fish are struggling now think about what it would be like if an untold number of unfindable dead CRS were rotting in the tank as well! I am going to refer you to a little trick that a1matt taught a number of us. Get a big...

One thing that screams out to me as a potential problem is that your Kh is 0. Your other parameters don't appear problematic and 50% weekly WC's will reset toxic levels of anything. I would add some crushed coral shell to the tank, or if you are using RO for WC's start using some tap-water and...

Well McPhil, you certainly do stock low for 240l! As to why your nerites are dying you still haven't told us your water parameters. Nerites will head to the surface and stop moving when the CO2 is high/ water is acid. Also, what kind of nerites are you keeping? Perhaps the ones you have are more...

From the stocking of your tank I can see that it is small. If your Ph is above 6.5 and your Kh is above 5 you can be almost certain that your nerites are starving to death. Nerites will NOT eat any prepared foods deliberately no matter how hungry they are. They behave like robots, pushing...

Post this in the For Sale/Wanted section. You will get a better response.

How many Shrimp do you need to start out with to ensure that you can maintain a viable breeding population indefinitely? 20 enough?

Does this mean that your assassins are not killing your Clithon's (except the baby ones?). Have you had any other survivng veligers? Pretty cool!

Good info on Theos here. http://mikes-machine.mine.nu/Theodoxus_fluviatilis.htm

Here is an interesting account of the sponges that come in on the Sulawesi Tylomelania 'Sponge' sp. http://www.crustaforum.com/board/showthread.php?t=1286

Tell me this isn't a picture of your snail (first picture on the left, first snail on the left) http://www.weichtiere.at/english/gastro ... water.html and apparently they lay eggs both on their shells and on other objects. I think we have a match!

Hmmm, sounds like you have Theodoxus Fluviatilis. It is a freshwater nerite that is capable of breeding in full freshwater and carries its eggs under its shell ( although you describe them laying on dark surfaces...). Its coloration is also very variable with stripes, dots, and combinations of...
