When i got my aro its would eat sticks and goldfish. When i kept it with my sting ray it would only eat live worms, black worms and frozen shrimp and wouldnt look at anything else. I took him out of the ray tank because i couldn't afford to have him eating all the worms. But he wouldn't go back on sticks, so i starved him and put him in a tank with some of my cichlid and the next day started eating pellets.
I weaned our Silver off goldfish using the little rosies, not enough to get him full then I placed Hikari sticks in the tank. Once he started munching down on them the rosies stopped, now he accepts all types of floating pellets, prawns, I just ordered some krill so we will see how that goes...so far he hasn't eaten fd crickets. Nevertheless, he is growing like a weed, coloring up nice. My son for the first time hand fed him prawns last night...good luck keep at it you will find a combination that works for you.
mine eats cichlid gold pellets. jus keep throwin them in. sooner or later they'll eat it. my aro went almost 3 weeks before he even tasted them. but eating n spitting out shows he has interest. just keep trying. mine gobbles them up now and has showed massive growth now that he eats them. i needa get my smaller aro on pellets =x
