I have livebearers and bristlenoses, so I tend to feed a lot more veggies. In fact, the platies, guppies and portholes in the main tank have pretty constant access to veg nicked off the bristlies. Oh well, it keeps them regular. Other than that, catfish tablets for the corys, occasional algae wafers for the bristlies, flakes for everyone else, and a twice-weekly treat of jellied bloodworm, daphnia or brine shrimp for all the communities.
The ticos are a different matter- they have proved awkward to get to eat. Atm they are living mainly off live daphnia and algae from the tank, but I am trying to partly wean them onto baby powdered flake food (they won't take anything larger).
