Guys and ladies.. One of my Silver Aros is a very poor eater.. he just does not seem to bulk up.. I got him say about 4 inches in Jan and now he is about a foot. Long but absolutely no mass.. He is on pellets now.. eats like 12 pellets a day thats it.. feeders once a week(guppy or goldfish), shrimps, bloodworms.. I'm concerned cos I got another aro at the same time about 5 inches and he is like a foot and a half.. solid size and vibrant colors.. now is there anyway i can bulk him up and make him eat better? please let me know.. cheers..
