my tiger barbs keep dying slowly and are now starting to have a bloody spot behind the belly fin I do not think ammonia is the problem, they get more listless over time( few weeks) and stop eating next I find them dead on the bottom of tank, help
welcome to the forum by the waycan you post your water parameters, tank size and tank mates, tank maintenance routine and anything else you think might help the members to help you.
Ammonia must be 0, fish-in cycle is in progress, you need to be doing at least 50% water changes daily (or as many as needed to have 0 ammonia every day), watch the nitrite too, nitrates aren't much of a concern.Yes, my temp is 72, ammonia was under 1ppm and nitrate was I think too high the pH is around 7.8. I did a big cleanup the other day and brought nitrate down and will do again on the weekend. the albino tigerbarb has some bloodstreaks on the body.
Sorry, I have a 10 gallon tank with one normal tigerbarb and a pleco, Iwill not add new fish right now.
