I just noticed this morning that one of my harlequin rasboras has a white ball on the end of one of his fins. He is acting normally and none of the other fish in the tank have any white on them. Water parameters are great - 0 ammonia, 0 nitrite, 7 nitrates. Do I need to treat with anything? (I think I added a photo.)

Sounds like ick... You could treat with medicine and try raising your water gradually to 80F. I've had luck in the past saving them unless they get white fuzzy eyes. I've found they're too far gone in that case. Good luck!
