A few weeks ago I watched a video of a guy who built a pool section for his fire belly toads with a section of plexiglass and 100% pure silicone. I tried it out and used a 36"L 18"W tank and the pool section was made 15".
The two firebellies I have certainly like it, in fact they spend 99% of their time there so is hard to feed them. I only once or twice seen them on the other side chasing a bug which I'm worried they are not getting them all. I shoo them over to land with a leaf during feeding but one just jumps immediately back into the water. Is there a chance they are going onto land during the night?
