yeah when it comes to frozen food the oscar goes to town and eats more than all the otehr fish put together...what what he eats in frozen he lacks when i feed live...the tems devour 50 small feeders in a matter of mins...i find that with frozen food the tems seem to wait till bits fall off where as the texas and oscar go fore the actual blocks whether it be BW, BS,BH...try feeding in 5 min intervals that way the oscar will (should) be full when it comes time th ethe 2nd or 3rd feed!
