http://www.qualityexotics.com/ Had some really nice Gold Terribilis, you can look at the pics on his site. I saw them at the local show, and they were awesome looking.
I would put in a vote for Leucs though, you could get 6 or so for that large tank. Mine are very active and very cool frogs.
:I have a 55gallon well planted on the floor and planted tree fern panels 3 sides it has a waterfall into a small pool in one corner. I have a misting system and humidifier plumbed in to it now i just need to decide what to place in there?
