Nina Posted September 10, 2022 Share Posted September 10, 2022 I received some juvenile chili rasboras about two months ago and, after letting them grow out in a 5 gallon tub, moved them into a 10 gallon planted tank with three green rasboras last week. The chilis are still tiny, but they seemed hardy during the grow-out and had colored up nicely. It's been a week in the 10 gallon and I've noticed discoloration on them. On the first half of their bodies they have a yellowish color and some subdued patches. They are still moving and eating well, but I'm not sure what's happening or what I should use to treat them. It seems to be affecting almost all of them. Ammonia - 0; nitrite - 0; nitrate - 10 ppm; GH - 40 (low, but similar to their grow out tank); PH - 6.4 (low but similar to the grow out tank); Chlorine - 0. water temp is around 78 degrees Fahrenheit. I've seen a similar disease in one neon tetra months ago -- it started with discolored patches, didn't respond to meds, and eventually wasted away. It only affected the one tetra and I eventually euthanized that fish when he became very emaciated over the course of a few months. It didn't spread to the others and that school was moved to a larger tank last week before adding the chilis to the 10 gallon. This seems to be affecting most of the school at this point. Is this bacterial? Fungal? Stress? The three green rasboras are a little larger and faster, (there are 8 chilis) but everyone is getting plenty of food (baby brine and some crushed up flake food). There is more flow in the 10 gallon than the grow-out tank, so I may turn off the filter for a bit. Any ideas how to save them? It took me a really long time to acquire these fish and I just LOVE them. Link to comment Share on other sites More sharing options...
