Om interested in keeping firebelly toads, I have a 150 gallon tank and was wondering how to set it up, the tank is 6' by 18" I was thinking of making it 4' land 2' of water, is this a good water to land ratio? Also what would be the best substraye to use, what are some good plants for a tank this size, and how many toads would live in here comfortably? Also with six feet just seem like a lot of space for just toads, would I be able to add some salamanders or newts, or another type of toad or frog? Thanks in advance for all ur help
