Being that the question is really about a specific frog (although you don't tell us what type), I would have posted the question in the sub-forum for that type frog. Then for sure you'd get this question in front of those that have a better idea about the needs of that frog. There are active members that I never see respond in this forum and they tend to stay only in the sub-forum for their frog. IMO, this sub-forum is for discussion about construction and maintenance of the viv and related components.
But then again, the forum seems to be at an all time low for activity.......................... You don't mention the specific type of toad... was it a budgett's ?? There is a
care sheet stickied in the
budgett's sub-forum that might give you an idea of appropriate size.
