New cool idea

[Kurt]

You can mix treefrogs with fish. I do. What you will need is a half full aquarium with drift woood or other similar object poking out of the water for the frog to rest on. Pick a species of treefrog that will eat the moment food is presented. White's, gray, green, and barking treefrogs are all good candidates, as they will need to be fed outside of the enclosure. Red-eyes are the last frog you should pick for this type of set up.
Fish don't matter as much, as long as they are not big enough to harm the frog or are a small surface dwelling type of fish such as hatchetfish. Don't mix anymore amphibian species in the enclosure either.

I'm rethinking the fish idea-it seems like more trouble than it's worth, and I also don't want to reduce the amount of usable space for the frogs. How many white-lipped treefrogs can live comfortably in a 55? I also know that white-lips get BIG, so what kinds of plants could I use? Also, how do you sex white lipped treefrogs? I'm thinking about 1 or 2 males and 2 or 3 females-I'm not going to get more than 5 frogs.
