I just recently bought a newt that was called a warty newt at the pet store I purchased her from (I'm assuming it's a her; for now we'll go with it.)She has a crest going down the middle of her back, a yellow belly with black splotches, and a sort of orangish stripe going down her back as well. Other than that she's brown, and very thin. I can clearly count her ribs and to be frank about it she has a very bony butt. At the store she shared a tank with a bunch of toads and the owner said that she was purchased about six months ago with three other newts, and the newts and toads resided together. He also told me that I should feed her small worms from the bait shop and that I didn't need to cut them up. At home the newt snatched up a worm right away (after blowing off a coupla crickets) and began swallowing it...But after a long struggle with that she spit the whole thing back up. I don't know if this is incidental or not, but she spit the worm back up right after I brought the newt that was residing in the tank previosuly to her out of his hiding spot to feed him, as well. He's smaller and they haven't made any lunges at each other, but I thought either the worm was too big or she brought it back up so she could be ready to fight if need be when the other newt resurfaced. Either way, her thinness concerns me. She looks undernourished to me, and she moves more slowly and stumbles more than any newt I've ever seen before. Does anyone know if it's possible that she's supposed to look anorexic, and if not, what do I do to fatten her up?
