Well, I went out and bought the little guy some stuff. I could not find a shallow water dish so he is using a glass lid that sits snug in his substate. He has a branch to climb on but prefers laying on the substrate. There are two of the tiniest feeder fish I could find, now swimming in his water. He went into the water a bit but only to drink. Later, he re-visited the water but did not get in. He just looked at the fish but no attempt to eat was made.
Thank you all for your wonderful suggestions!!!! It has been almost a week now. Hopefully it will be a lot longer.
