I can't get my 3" baby delhezi to eat anything! He just lies at the bottom hardly moving, then burst to the surface to get air, but that's about it. I've tried frozen blood worms and shrimp pellets, but still no dice. He's in a ten gallon holding tank with gravel. I'm trying to get him as big as fast as possible so when I put him in my 125g tank the arowana won't swallow him whole. He is as thick as a pencil and only about 3" long. Help please and thanks!
