Do astatotilapia aenocolour need low protein diets? I had 6 but lost one to bloat from the crap they were fed in the store, swelled up horribly on the second day and just died. most of the others seem okay and one is even holding, but a few have not eaten in a few days and are still looking rather healthy. I've seen some of them, mostly the male, picking at the glass, driftwood, and rocks I currently feed NLS pellets and bloodworms. should i be feeding a higher fibre diet to these fish?
