my favorite fish food? Well I feed a variety to my fish, angels, candy cane tetras, corys, pleco, platys all in a 90 gallon tank. Kens sinking wafers, Tetra color granuals, Hikari daphnia, Tetramin flake, Aqueon Shrimp Pellets BUT Repashy Soilent Green wins over here. All my fish hang around the little dish at the bottom of the tank that I put it in, absolutely NONE is ever left. If I dont put in they swim around their dish like Indians circling a wagon train, LOL I did try Repashy Bottom Feeder for the clown pleco but alas, it wasnt a winner.
