Does anyone on the list have an idea that can help?

I purchased a pair of U. pietschammi from an importer. The female is small, stout, active, and a good eater. The male is older--about 5.5 inches total length. He arrived looking thin but not emaciated. Since he is alert and active, I didn't worry at first and was confident that he would fatten up. But I have had him for 10 days now, and he shows no interest in food and has gotten thinner. A couple days ago he received panacur and flagyl. Hopefully, removal of parasites will generate appetite.

Other care parameters are good. I have kept Uroplatus for several years and have bred U. henkeli. I have four other U. pietschammi, including the new little female, and they are all thriving.

Any ideas? I would hate to lose him.

Thanks,
Mike
