I fed him probably a 4" worm as I described.
This was AFTER he had 2-3 snails...he took about 3 nips off one end of the worm, and another off the side, and was done.
I left the worm in there as I cleaned some other tanks at work, just to make sure that he had his full, and took it out 30 minutes later when I saw that he was done.
Sounds like feeding wont be an issue...the only question now is do I medicate for internal parasites just for safeties sake?
