The seller has pocketed your £20....and used a cheaper 2nd Class service.
That's not the fault of Royal Mail...there are terms and conditions for sending items...fish being prohibited.
I've sent hundreds of packages through Royal Mail and never been let down on any delivery...
Depends when the Post Office received the parcel?
Or which day it was collected from the seller?
Royal Mail start their delivery's after 9am as the Postmen only do once over the ground now!
Those changes happened a number of years ago....the 4pm time line might be temporary due to the large...
Ideal Number to Keep – Though not gregarious in the sense of schooling fishes it does seem to require interaction with conspecifics and displays more interesting behaviour when maintained in numbers, meaning the purchase of no less than 4-6 specimens is recommended. Groups develop noticeable...
I have a number of years ago they are not as boisterous when in larger groups, they tend to bicker every now and again with each other!
I kept them with Tiger Barbs and found these could be a bit more boisterous!
You shouldn't have any problem with larger numbers in your planted tank!
There are a few theories on fish reacting badly to large water changes!
The new fish purchased from the local fish store may not be acclimatised to their new environment yet.
There is a lot of compressed Co2 in tap water which could increase the dissolved Co2 in the aquarium to an...
Concrete extra hard...... London Style!
I've also had about 8/10 Tiger/Green barbs in a 4 foot aquarium.....absolutely stunning fish!
They never fin nipped anything...space and hiding places could be the answer...maybe!
Serpae Tetra...nice fish!
But very aggressive towards each other at times.... and other inhabitants!
I've housed them in a 4 foot aquarium in a heavily planted tank and the fin nipping behaviour wasn't as bad!
Actually had some offspring.....Hemel Tap Water!....;):):thumbup:
I don't think you can distinguish between the Male and Female gender at the juvenile stage!
I could be wrong though.....Tetras will eat eggs and young fry if given the opportunity!
If you have a very heavily planted tank, the offspring may have a higher percentage to surviving to adulthood...
Indeed....you don't need to adjust your tap water.
Cardinals with do well in hard water......if your interested in breeding them you will have to alter the water chemistry, to suit their breeding requirements!
Incidentally I have had a few Tetra fry " not Cardinals/Neon's" appear occasionally in...
Best move the little guy/gal to another tank....if you have one!
Nice clean water and add some Pimafix.
Even if its not fin rot, this procedure will help keep the wounds clean from secondary infection!
Poor environmental conditions can kick start internal bacterial infections.....regular water changes and light substrate cleaning will improve the inhabitants wellbeing always!
Dropsy/Pine Cone disease/Bloat......is nearly always attributed to poor water conditions and poor diet!
I'm not sure but.......
I think it's a tad early for spawning !
Give them a year to mature...then do regular large water changes. ....with water a couple of degrees lower in temperature !
This usually encourages spawning. ....feed them a good variety of food....frozen/pellets/live worms!
First Ember.....could be Neon Tetra disease.:(
Second Ember tetra has White spot (Ich):(
Plus seems to have a early stage bacteria infection....coming under the term dropsy.
Swimming in a uncoordinated manner
Guppy's have high aeration in fish store tanks as all fish bought from the local fish store!
There's the clue....try adding some aeration for a day or two to get them acclimatised to a Co2 tank as Jordi stated!
Strange they meet their demise after a water change...this could be the clue.
My municipal water company have a habit of overdosing chemicals...you can actually smell the product they use.....smells like Chlorine.
That maybe your answer.
Its a bit of a mystery...Bertie.
I live in Hemel Hempstead.
I experienced this fish behavior after a large water change a few years back.
I wasn't dosing fertilizers at the time.
I had large Tiger barbs at the time and a few started losing swim bladder control...spinning/jerking...as you...
Don't feed them for a day...then every time you pass the aquarium add a smidgen of food this may help to get them out from hiding and familiar with your presence.
Before you do maintenance feed the fish and also do that after water changes and maintenance's....this should help ease their...
Your neon's haven't acclimatised to the lower Oxygen levels in your tank.
I would do another water change ...asap.
I don't think its your Co2 set up going haywire. Neon's are very sensitive to higher Oxygen to lower Oxygen transfers usually when Co2 is being utilised/used.
Remember if you...
This is what I would do...... turn off your filter remove the fish into another Tub/tank....make sure its clean I would wash with bleach first and rinse thoroughly.Use a sponge filter to achieve some aeration and a heater.
Clean your filter in dechlorinated tap water.
Gravel clean the...
I live in Hemel.
Ive had cardinals for years......there's in no problem with hard water as Ceg said clean water is the priority and that's correct.
Soft water is probably needed for breeding purposes only.
Just make sure the water is approx the same temperature as the aquarium water...
That's the beauty of having a planted aquarium....you never know whats lurking in the hidden depths.
Anyway that's a nice find and very rare...... well done.
Its great when egg laying fish survive in a community set-up..... its all the more satisfying that the fry have lived long...
