I have a 125 Gallon 18" tall x 73" Long x 18" Deep, which I am going to insert a divide in the middle. Its going to be Dart Frogs (Azureus) in one side Pygmies in the other. Hoping to have it done by mid summer, I will probably set up a blog for it when I get all the plants and junk together.
I used my 10 gallon aquarium for my yellow spotted salamander, I made it into a living terrarium, you could definitely use it for pygs, salamanders, frogs, etc.
I know that it's not cham related, but Phantasticus would be fantastic IMHO.
(oh, and you can hire me to take care of them too. I'm cheap, I work for food. )
