taming cichlids

My acei's were very good at eating the spirlina sticks for my hand, the
rest are too nippy though, they get the fingers more often than the food,
especially the bumbleebees. Since the addition of the large eyebiter, I dont
really try hand feeding the africans anymore...ouch!
I feed my polypertus birchirs with a stick and am hoping to get them to
take from hand, as well as my fire eel, but he is still to shy to eat from a
stick. I had oscars that were good at taking from hand, but as they got
bigger, I tended to just throw the food in, just in case
