well monte is actually in a 12 gallon right now so he is in a closet if you think the 24 gallon is an apartment lol, but really the 24 will be more then enough if its going to be him and a couple pieces of rock, i just am away so much that i need that big of a tank so it can stay stable easier, also because im going to be doing alot more studying of them, going to see if giving them a large tank will help induce more natural behavior such as swimming and multiple burrows and such
