I am new to having fire bellies. I got two toads at the same time about a month ago...Chester and Lester.. One toad has died ( Lester ) and I don't know what from. I was cleaning the tank and when I was done put both toads back into the tank and Lester starting opening and closing his mouth and then flipped over on his back and that was it. I do know that both are male. When I first got them they barked all the time and were very active. Now that Lester has died, Chester is not barking or as active. He is still eating and pooping normally. He does however stay mostly out of the water unless I open the tank screen then he hops into the water. Is this normal??? I clean the tank weekly with a 100% water change every time! He seems to also look normal. His color hasn't changed. I keep the tank temp around 72-74 degrees with the water temp at 74 degrees. I dust his crickets with Repti Calcium with D3 once a week. I feed every other day. Please help!
