the goldfish get pellets every other night or so for now... i do this because they're tightly packed at the moment.
also, there's plenty of elodea for them to munch on (and they do take advantage of it) and they also steal the algea wafers from the pleco if i put them in too early.
as far as the pleco goes, he's basically been fed every couple days with regards to the algea wafer theft. i try to feed him more often, but it just doesnt work because of the goldfish. in addition, he's eaten two snails at random.
fortunately, i've found someone with an algea infested cichlid tank that can take the pleco until someone is willing to buy him. and hopefully the cichlids will allow him to eat his algea in peace. poor little guy 8(
the betta is a scavenger if i ever saw one. in addition to eating / picking at the antennae of the snails when they were still around, he eats goldfish food, algea from the wafers, and a tropical flake food that i have, as well as a shimpy/ krill flake food. and he basically just eats anything he can get his grubby litle fins on.
