Chocolate Betta...she writes that the plecos are going to a 50g not 30g. Probably still too small for TWO common plecos, but not as bad as a 30g :)
MidTnBetta: I honestly don't know if you can mix Rid Ich Plus by Kordon with antibiotics but DON'T stop ich treatment! The fin rot can more than likely wait to be treated (especially if he's asymptomatic), more important to get ich completely gone. Besides, the water changes you are doing are likely the best medicine for the fin rot and should help it in any case. :)
