Hi everyone. A couple months ago i came on here woth my betta obby who started sinking and then died. My other betta roxy has come down with the same thing. Her tank had an ammonia spike and she seemed lethargic and was sinking, so i moved her to obbys old, smaller tank to monitor her and fix the ammonia spike in the other aquarium. I thought she was getting better yesterday, but tonight i checked on her and she was super pale, almost “wheezing” (if a fish can do that) and looked dramatically worse. Shes not pineconing but just really white for a usually clearish fish. I moved her to my bucket so she has shallow water but i did the same for obby and he only lived 3 extra days. He was old though and roxy is much younger, so she’s stronger, but i still dont know how to help her recover. How can I save roxy?
