jonpwn, please don't get the impression I'm going to lay into you on this, but I've seen some people on youtube get ripped apart because they don't build considerate enclosures for their toads.
What you have to the side of your tank appears to be a cold wet plastic enclosure. Could be just naturally dark soil, I don't want to know, because there is an equally long scientific mumbo jumbo about the different elements, and yellow cake uranium or something.. idk. Fowler's do seem to enjoy water a little bit more than others, but most of my toads like it dry and warm. With what your going for, you could make and interesting travel case, assuming your not ready to build them a nice display case. You could probably invest no more than 50 american federal notes and have something impressive. Luckily for you most of us are willing to help you learn how to step up your game. social platforms like this can be more dynamic then searching Google, I had to ask a lot of compatibility questions about everything. It's never ending. cute toads though, I foresee a lot of nerd girls gushing over them.
