Before the red bellies i had a true alligator gar that grew to 3+ feet in that tank, he was getting so big I released him in my local lake. He was the COOLEST fish i have ever had. I made a few vids of him eating huge koe fish. Ill try and dig them up later and post it tonight. You guys would get a kick out of it. The red bellies are alright they are just so skiddish, my son wanted them and i tryed to talk him out of it ( I wanted a silver aerowana that the lfs had) but he got them anyways. They eat mostly shrimp and cut fish hardly any feeder fish, keeps them healthy. Every once in a while we will throw a dozen feeders in and watch the destruction. LOL.
