Feed mine twice a day (with Hikari large cichlid pellets) with an occasional period where I skip a few feedings so it may drop to once a day. There are days where live food is added as a treat besides the double feedings (during the winter it is just crickets and during the summer he gets nightcrawlers and crickets).
Regular feeding is about 5-8 Hikari large cichlid pellets (this is usually enough for him to eat all except for the last couple pellets - these are mouthed and only half eaten. Then I know feeding time is over.)
The uneaten food is then handled by the other inhabitants - a firemouth, 2 giant danios and 2 catfish.
