If you pay attention to the way cichlids eat (especially O's) you'll notice that pellets are crushed at the back of the throat. That's why you see food particles coming out of the gills. They don't swallow the pellets whole... so there wouldn't be a huge amount of expanding in the stomach... if any.TwistedPenguin;3082329; said:There's less chance of pellets swelling up insdie of them and causing problems if they're smaller. My full grown Oscars still get the medium size pellet because of that. It's probably just an unfounded worry of mine![]()
