Ever since I've tried to keep shrimp in all different forms (Cherry, Amano, CRS) they've all died. Many have died for no obvious reasons with fish being happy and algae there to be eaten. Recently, a large amount died during over dosing TPN+ to cope with the few days off in between due to holidays and I've just increased dosing TPN+ to 2ml per day and the remaining two Cherry shrimp have died, one each evening. There's been loads of things I've done, the main one stopping doing EasyCarbo as shrimp are sensitive to that. Everything I try and do to keep shrimp fails, good tank routine with water changes and feeding now and again due to them having algae to feed on. I'm completely stumped, I know that other users cannot keep shrimp for various reasons, but I'm worried now that I don't have shrimp in there, that I don't have a clean up crew. In addition, when I tried to keep snails in my large tank, they died too (assains and nerites) apart from the pest snails. Any advice would be greatly appreciated as I don't want to keep killing things.
