I've been following this thread for about the last 10 pages... Poor Rocky, I'm so glad he's in better hands!! Thank you for rescuing him.
Anyway, I wanted to share some info that you might find helpful, regarding soaking him in something a little more "potent" than water. Something I've heard recommended very often in tortoise care, when it comes to sickly hatchlings, especially those that won't/aren't strong enough to eat, is to mix baby food into the water and soak them in that. Carrot is the common recommendation, for the vitamin A content, since eye problems are common in sick baby torts--maybe it'd be good for Rocky, too, since he's having eye troubles.
Another idea is to mix liquid bird vitamins into the water. Either one should help in getting some extra nutrients into him.
Hope it helps. I'll see if I can spare a few dollars for the rescue fund, too.
