Hi, I'm new here. I have had this betta about a year or so, and in the last few months he developed a white ball thing on his dorsal fin. It was small at first, but has gotten bigger and bigger. I removed him from the 10 gallon tank he was sharing with some cory cats and an algae eater, and put him in one gallon bowl with a small heater. I have tried anti fungals and antibacterials.
I gave him tetracycline for a couple weeks, then he seemed to feel better, so I stopped. The next thing that happened, he got fin rot and lost his fins behind the bump, so I started the tetracycline back. He seems to feel ok...he eats well and is energetic..but the big bump doesn' t go away. I can't find any pictures of anything else like it. Does anyone know what this is?
I will try to post pics:
Does anyone know what this is and what to do?????
