If that is all you have in the tank I would suggest only feeding them at most a tiny pinch of flake food a day. Too much food will decay in the tank and kill the fish. If the pleco is in the tank you might want to try sinking vegi pellets for him. 1waffer every other day (if it disapears) is good. If you want to put more fish in there I woudl suggest guppies and other small tetras. You should only add a few (2-3) small fish at a time and you should not have any more than 8 small fish in a 10 gal. Good luck!
