Hi Mary,
Not sure if you've had one like this before but here goes.
My beta Lucky is about 2 years old and about 4 months ago he started to develop some growth on his side. I attributed this to an unknown tumor that nobody seems to know much about. He seems healthy and happy otherwise, I clean his water twice a week, he sits on my desk at work and we have daily chats and sing-alongs (he does the dancing and I do the singing). I am concerned now though because it appears as if the growth is beginning to peel or deteriorate, almost like a wart that had been treated with Compound W. Any thoughts or suggestions? I'd really like to prolong the life of my beloved desk mate as long as possible. One more thing, his water is always kept at approximately 82 degrees and is crystal clear. He also eats a weekly diet of betta bites, with a few blood worms thrown in from time to time as a treat--not too much though, don't want him constipated! :-)
