Justin, My wife and I went to Reptiland about a month ago and saw that display. It was nice, although when you are interested in frogs, there can never be enough displays. Dartfrogs were represented, along with mantellas, bombina and xenopus . The other "less common" frogs in the collection were pretty cool, especially animals like the budgetts frog (Lepidobatrachus laevis), I've never seen an adult. My wife took a lot of pics, if you want I can send them or post a few.
