First off, Thanks for all the great info...

Welcome to Frog Forum You have a very nice Chacoan Horned Frog. Ceratophrys Cranwelli(Brown Cranwelli). The Argentine Horned Frog is Ceratophrys Ornata or Ornate Horned Frog. He's cute by the way.

Thanks for the clarification. How can you tell the difference? They look the same. Is it the pattern?

So I hooked up his tank last night and this morning he was gone. I literally can't tell were he's buried and he's a big boy, the size of my hand.Here's some new tank pics with new fake plant,a great rock background I found, water dish and some other stuff.
