My Male Betta is sad, and appears to have developed some fin rot. The temperature is at 80 degrees and I have added aquarium salt. he is in a 20 gallon community tank. I have not filtered out the gravel for a while, so I'm about to do that. Otherwise, how should I medicate him? Should I use some bettamax in a little quarantined tank? Or is there any way to medicate him while he's in the big tank?
Thanks.
Thanks.
