I have a friend whom I'm getting into planted aquariums, also gaining a liking for Crypts. While I was visiting these past few days, we found some Red-Backed Salamanders. Of course, she wanted to keep them as pets :P so we temporarily put them in a 6g Eclipse tank I just gave her.

We talked about it and heavily considered going with a simple 10g terrarium setup for some(2-3) salamanders. Going to go with all emersed aquatic plants, mostly crypts, but possibly swords, anubias, moss, etc... as well. Tank will be covered, probably a DIY plexi cover with a small grid of airholes - enough for the salamanders, but not too many to affect humidity in the tank.

Just a few main questions:

1. What would be the ideal substrate setup for this? I'm thinking gravel bottom (have a lot of flourite left over) with a small layer of peat & some good soil.

2. Lighting - Does emersed state use same light requirements, or would it be different?

Any other suggestions/criticisms would be appreciated.
