I need help with my Senegal Bichir. Just a few minutes ago I noticed he has a red lump on his side. So far he is still swimming and eating normally. My water parameters are Ph 5.8 NO2 0 (NO3 60 Yes I know I will work on getting that down) GH 80-70 KH 10 Ammonia I don’t know but it should be fine I have great filtration. I have had the aquarium running for about 8 months and I have had the bichir for about 3 months and this is the first issue I have had. I feed my bichir hikari carnivore pellets. So far all I have noticed is the red lump and all my other fish are doing fine. I will post a picture please help me identify the issue and help me find a solution. If you think I need to separate him for treatment I have a 10g hospital tank just tell me what I need to do. Thanks for any help you guys can give.
