Hi, everyone.

I've recently had a 50 gallon fish tank come into my possession, and I want to stock it with something unusual. Frogs, reptiles, amphibians, etc.

My question to you is: What can I keep in this tank? It's about 3 feet long, 2 feet tall, and 1 and a half feet wide. In the centre it's about 2 inches wider than the sides.

Thanks!
