Thanks for the compliments. The tank is a 20g (12x24x16). The back is foam with embedded wood, the bottom is egg crate with leca and coco fiber mixed with creek sand (5%) and dirt from a clean source (5%). The moss is a mix of three types. One is tropical sheet moss from Black Jungle, the pillow (?) moss is from somewhere I can't remember, and the long fiber sheet moss is a local harvest. I found a rock quarry with some really sheltered areas that grow the stuff. It is a bear to get to but worth it. If anyone wants some, hit me up and I'll see what I can do.
The tank is room temp, currently 68.5, but varies from 63 to 77 depending on the season. The lighting is a coralife dual tube T5 light. 24W x 10,000K. There are 4 marms in there and they are just as happy as little clams. There is a little water area and when they start to like the water more I have another set-up that is 80% water for them.
