I have a friend who has a 50 gallon tank. She's trying to decide on a type of lizard or frog to put in there. She seems to be leaning more towards frogs. She thought about pacmans, but they cannot be kept together, right? (I had been told they could not because they would fight.) Then we thought about using a divider and having a water area in the middle and then a land area on the ends of the tank. But another friend is trying to convince her that it is a waste of a 50 gallon.

So...suggestions and opinions?
