Re: 18 x 18 x 24 Exo Terra 4 Green Sirensis
I'm a big believer in branches in most of my thumbnail vivs. It makes all that empty air space in the middle, much more usable.
If you are just looking for a few "bread and butter" plants, I can probably cut a couple/few things for you.
As far as depositing sites, mine use broad leafed plants, the glass side walls, leaf litter, and in completely horizontal, dry film canisters. In my group of 4 green sirensis, I use 2 horizontal canisters, and 6 at a 45 degree angle, 1/3 to 1/2 full of water, for them to deposit tads in. I don't bother pulling any eggs. I don't think I've ever pulled a single egg from them. They do a very good job transporting and keeping all 6 canisters full.
