I have always felt that lampreys were the most monsterous looking fish out there. Is it Possible/feasible to keep them? Does anyone here keep them? how big do they actually get? Do they require a chiller? I have heard of people keeping small parisitic catfish before and feeding them with larger fish every once in a while and the fish being able to live. Is all Lampreys eat blood? I am really interested in keeping them but can find almost no information about keeping them alive except to use as bass bait.
