I was wondering if there was a non-toxic epoxy that I could mix with aquarium gravel to make a permanent gravel base for my firebelly toad tank.
Also, in relation to the water level of the tank, how deep is too deep? Right now, they start out with about an 1˝ to 2 inches of water. When they're in the water they tend to stay to the deeper parts and occasionally swim. They're pretty active, so they tend to pound their dry land down into the water.
