Some folks found a "walking catfish" crawling down the sidewalk , in S. Fla. At least a mile from any water.
Knowing I was a fishnut ,they called me. The fish was about 9 in. long, dirty,and all mouth. Of course I took him in.
I put him in a way too small 20 gal.
He would polish off a 2 oz. can of fish food in a day. I had a dog, so I tried feeding the catfish dry dogfood. He ate that, smalll pieces of chickin, and allmost any thing else I tried.
As my tank was too small, I gave him to a bar over on the beach, ( after making sure they knew what they were doing ). Big, well kept,freshwater tank. Last time I saw him, he was fat, and doing fine. The bar patrons had contest to see who got to feed the catfish for the week. Lucky fish.
