FIRE BELLIED TOADS MALE OR FEMALE?

Chinese fire-bellied toads, need some help.?

• well I have 2 questions. We have 3 chinese fire bellied toads, 2 brown and 1 green. The green one is alot smaller than the other 2. I feed them crickets and I feed up the crickets so they are full of good stuff for our toads. Robbo (the green one) was small and sick looking a few months back and I got some wax worms to fatten him up a bit as I had read they were full of fat and should only be given on occasionly. He got fat and was doing really well. But he's back to how he was before and well I got some more wax worms today but he didnt want any (I have a plastic tank I put toads in with the worms as wax worms end up lost in the gravel of their tank) But that could be coz I feed them crickets yesterday. Any ideas on how to keep the weight on him?? Also can they change colour?? Coz robbo has brown markings on his legs that werent there the other day! Will he end up brown like the others does anyone know??

• Answer:

  I would just feed them wax worms every few months or whenever he looks thin. You're supposed to give them something different once in a while anyway. Try putting the wax worms in a dish so they don't get away. If Robbo is a lot smaller than the other two, maybe he's stressed out (that would explain why he's thin) or they eat all of the food before him. He might need a smaller tank. My toads (same kind as yours) have changed colors (maybe to camoflauge?) and they're all fine.
