Well, I spoke to a marine biologist today and he said the fish was an armored catfish. He showed me over 30 pictures of the ones he has seen in florida. And the fish I caught in the net was an exact match to a one of the photos.
He indicated that that are really close to 50 different type species of these fish. All the years I have been fishing in florida, I had never seen one. He said that lake monroe is full of them. They tend to like shallow runs in creeks or moving water. From what I was told, you don't catch very many on a hook as they don't eat baits like most fish. Thanks for all the help.
