I don't know if all red devils are like this, but mine is a high-maintenance cichlid. Not a day goes by where I am vacuuming up his waste and scrubbing algae off the glass, as I can't keep an algae eater with him.
Is it the food I give him that causes him to produce so much waste? I feed him NLS 4.5 mm.
