i feed those a wide range of foods but have always used JBL novo rift sinking sticks as a main food. I also fed sushi wrap, shelled peas, blood worms, JBL Novo vert, Sera granumeat & granugreen. i have not had a bloat case ever, i think a good variety is very important.
Now that i have tropheus i stick to the sinking sticks, sushi wrap & shelled peas.
