This will be a paludarium. It will have a false bottom set 6" above the tank bottom.
Filtration: Multistage. The false bottom will support a Hamburger Mattenfilter (HMF) as per an earlier post of mine Tell me why this is a bad idea: Canister + HMF + Paludarium
. A SunSun 404B will power the HMF and return the water via a reverse-flow undergravel filter (RFUG).
Substrate: Not set on this yet, but I'll probably go with the coal slag from my deceased 55 gallon.
Scape: I really like the shape of the riparium at the bottom of this page http://www.aqua-rebell.com/aquascapi...uascaping.html
. I will do something similar to this using polystyrene pads and drylok as rocks. It will almost certainly have a waterfall.
Inspiration: A pool in a headwater stream
, but including crypts, lilaeopsis mauritiana, and dwarf sag underwater, and orchids, tillandsia, mosses, and ferns above water.
Fauna: Probably pygmy corys, my farlowella, otos, and possibly shrimp. If I don't do shrimp I may go for something to add some flash, such as cardinals, emerald eye rasboras, or pencil fish.
