tzarder

Yes, he still swims fine and is acting pretty normal. I am going to try the medication Colu mentioned and see what happens.

I have a Betta in one of my tanks that lost its tail and now has a white stump. Its been like this for a couple of months. He acts normal except seems to have a vision problem on one side. Wondering if anyone knows what this white lump might be. When we first got this one a couple of years ago, he looked pretty bad, had no tail and ratty fins. They grew back fine and looked normal up until this issue started. Temp is about 78, no ammonia or nitrites. Thanks
