I have 6 silver dollars, 3 Angels and a catfish. I feed them 2 blocks of Bloodworm and its gone in seconds, the fish dont seem to be hungry after this but i know they will eat if i throw something back in.? Is 2 blocks of frozen worms enough or should i be adding pellets and tablets aswell..? Once a week i throw in shelled peas and they scoff this also in no time....im worried that im either over feeding or not feeding them enough.All opinions welcome.
