I have a 250g tank in which there is a 11" silver aro and a pair of albino ruby red oscar of about 6" and 3 pairs of silver dollars .. I feed them with hikari cichlid gold and shrimpe... my aro just used to eat the shrimps but now it has started eating cichlid pellets also .. so I want to use a pellet which is good for both aro and oscar .. along with which i give shrimpe .. so please suggest which is good for both apart from hikari carnisticks
