I think I lost a couple unfortunately. I haven’t seen any bodies but haven’t seen all six together for a while now. I probably shouldn’t have added any tank mates in with them as they compete poorly for food. However the remaining darters seem healthy so maybe that wasn’t the reason. Some were rather skinny so may have been parasites.
they’re doing great, no they’re in a smaller tank in the cabinet. I would love to have them in the 1500 but I think the biotodoma would make a meal of them.
They have their own little spots which they defend quite fiercely however they’ll often whizz around the tank together, they’re a great species.Great! Would love to see some pics when you have chance. How closely do they shoal up, and how active are they (compared to, say, your typical Embers which tend to hang in a favoured spot until food shows up)?
Probably should have thought about this before I filled it up but does anyone know how safe this actually is? The cabinet is extremely well made but it’s made to have a tank sit on top of it rather than have an additional two in the cabinet. I already had one 50 litre and a 35 lite under there and all was ok, however this new tank is 70l. The 70 litre is replacing the 35 litre. Am I worrying too much or am I pushing my luck having this on the bottom too?

It’s not steel framed, it’s one of their double skinned units. That panel is floating with the feet you can see supporting it. There’s a total of 8 feet supporting the cabinet, with four in close proximity to the new tank.Is the cabinet one of their steel framed units? What is underneath the panel that the tank is sitting on?
It looks like there is a foot either side of the section the tank is on, so it’s likely fine, but you could always put some pieces of wood between the floor and the base panel to sure it up - I probably would, just to be ‘belt and braces’.
Some people don’t feed bloodworm due to supposed links to bloat. Do you feel this is an issue? Lots of reports on what fish feed on in the wild shows bloodworm to be a large part of their diet.Hi all,
They eat a lot of bloodworms and terrestrial insects in the wild. It would be really interesting to know what the insects were.
It is a bit of a strange one, but I think both parts are correct. I think this dichotomy occurs because you only get commercially collectable amounts of bloodworm in <"very polluted water">, where absolutely <"huge numbers"> can occur.Some people don’t feed bloodworm due to supposed links to bloat. Do you feel this is an issue? Lots of reports on what fish feed on in the wild shows bloodworm to be a large part of their diet.
......... This would be conjecture, but I visualise the microbial assemblage in a filter in the same way that I think about the <"benthic invertebrate assemblage in a stream">. In clean water (water with a lot of dissolved oxygen and a low Biochemical Oxygen Demand (BOD)) you have a diverse assemblage of invertebrates, including <"Mayflies (Ephemeroptera), Stoneflies (Plecoptera), Caseless Caddis (Trichoptera) etc."> with Tubificid worms (Naididae) and "Bloodworms" (Chronomidae) etc present, but as a minor component of the assemblage.
As pollution (BOD) increases dissolved oxygen levels fall and you lose the more sensitive species from the assemblage. At the same time the number of Blood worm and "Tubifex" increases. As pollution continues to increase eventually only the haemoglobin containing Blood worms and Tubifex are left, and these often <"build up to huge numbers">.
The "Tubifex and Blood-worm" scenario is the traditional view of "cycling", with Nitrobacter winogradskyi etc representing Tubifex etc. If you only ever look at sewage treatment works? You never find the Mayflies.
This is what I had heard previously. I am currently feeding frozen black mosquito larvae as it does trigger a reaction with me. However looking at your statement about commercial collection for bloodworms I’d assume black mosquito larvae would be the same if not worse considering they can survive in almost any body of water even if it is heavily polluted.
