You must feed those green sunfish. They appear to be waiting for the food wagon to arrive.
If those are green sunfish, I must have been wrong about there not being any fish in my pond. I don't know. I fished that tank for several years without nary a bite. I didn't stock any GSF, just OTS CNBG, Res, CC, and FHM. If so, it's going to change my pond just a tway bit. It will still be fun.
