Of course my new cory additions are diseased from Petco. Iv'e lost 2 of 4 pandas in the past two days and now my albinos are looking sick. I thought is was bacterial fin rot but now because of the fuzzy white appearence I'm thinking it could be Columnaris which is gram-positive no? I've begun treatment with Maracyn-Two but I'm realizing that this is only for gram-neg. Sholud I treat with Maracyn simultaneously? My perameters are great - 0,0,>10. Whatever this is it only takes about a day to kill the fish. Also one of my remaining pandas has a very disturbing symptom, his eyes seem to be collapsing in to his head! Any suggestions would be great.
Notice the white raggedy appearence:
