Thanks for the suggestions. Once I have some spare change to upgrade their tank it will definitely be a more "handicap" friendly environment. When I found them in the state that I did, I was shocked they didn't die. Despite their injuries they healed quickly and their appetites never seemed to suffer. I don't hand feed them. They manage to catch whatever I put in their tank and have grown. I'm guessing they're content because I do hear them croaking during the evening hours. They seem to carry on as if they still have their limbs
