My bicolor angel is in his 3rd week of QT and has a long green poop. He has already gone through TTM, a formalin dip, and 2 rounds of prazi. He is also undergoing his 2nd dose of general cure (metro + prazi). Does this indicate internal parasites? Or is that only if the poop is white? If parasites, what else can I do? He's eating like a champ (mysis, Ocean Nutrition pygmy angel formula, live blackworms, NLS pellets), but is hiding out a little more than normal.
