sounds good im starting mine off with prawn a floating cichlid pellets (only to save money when hes bigger lol) and then when over 20" long i will get him whole fish and large floating pellets as they arnt that much.
sounds good he will be very strong when you try to net him if he gets over 15"+ trust me lol i found out with my old one stronger then you think anyway. mine will be in a 4ft tank till he gets around 8"-10" then in a 5ft by 4ft by 2ft (4ft wide!) so he should be ok for some years.
