I have 20 Tropheus duboisi and need some urgent help. My tank had some gill flukes about a week ago but i made it go away with some anti biotics. Today i stopped dosing and put in the power filter. Now my tropheus duboisi wont eat and their poop is stringy and clear white. Their bodies seem normal size but i cant be too sure. They are about 2-3" each and are in a 100 gallon tank. if my fish do have bloat could you tell me how to get rid of it? thanks.
