Thanks Trohr-the toads really like it as well! They now spend as much time on land as they do in the water, hiding out in the plants and climbing over the driftwood. I'm having problems keeping the water portion clean and clear-I think my underwater filter is not capable of keeping up with 6 toads who bring in everything but the kitchen sink into the water.

You cleaning idea is one I will keep in mind-thanks for the suggestion! Finding that balance between what the toaders will love and what will be more convienant for me is a fine line I haven't found yet...but I won't quit until I do! Cheers.
