I know it happens, I know it's common, I know it's easily treatable - but its still hard to come home to a happily dancing
betta with half his tail fin missing

I watch his fins obsessively for any sign of infection - I've seen pin holes before, but a
water change usually fixed it and they healed right up. Today though, a portion of his tail fin is gone, and the ends of his fins have started feathering up. Although.. his pectoral fins have always been ragged... never figured that one out. The Vita-Chem seems to have helped the fin membrane grow back in degrees... I wonder if the current is too strong in there for him, causing him to over-strain his pectoral fins.
Done a water change once I saw it, I've been adding Vita-Chem to his water every day for the last two weeks, and now I'm dosing his food with Vita-Chem as well. I'll keep up the water changes and Vita-Chem.. don't want to medicate unless I absolutely have to... if there's no improvement by the end of the week I'll have to bring in the big guns. I'm thinking Tri-Sulfa, if I have to medicate?
Sigh.
