Thanks. The small goldfish you can see are the feeders I put in a while ago. Plus, he does not bother the two large ones. I thin he knows he cannot attack them. He is also fine with the cories, but sometimes I catch him chasing them, and gives up on them. I will probably be moving the cories to my 5 Gallon soon, along with the goldfish to make room for maybe a bass or a perch.
