FBT vivarium help

[Mentat]

First this to do is read this excellent care article: Frog Forum - Fire-Bellied Toad Care and Breeding - Bombina orientalis and relatives. Also, ensure the water is dechlorinated tap and the pebbles are large enough so they can't be swallowed by frog.

FBT's do tollerate each other, but they don't need to be kept in groups. Carlos already gave you the tips you need, and he is right about the pebbles. FBT's can be monsters when they are eating. They are not the best hunters in the world, and they attack their prey in a rather clumsy way. It's possible that they don't grab the prey but someting else, and if it will fit in their mouths, they will swallow it. I once saw one of my FBT's attacking a fruitfly, and he ended up with a mouthfull of moose. He just sat there, trying to get rid of the moose. He almost looked ashamed of what he had done. LOL!
