I haven't done a good job at memorizing my plants. I'll try to provide a closer photo so you can see for yourself.
When I partially broke down my Gemini pico tanks to lower the dirt substrate, this is where the two mopani wood pieces ended up, along with some plants. It was temporary, and then I just loved it.
For the light, I am actually using the bracket backwards, to give more height. With the little gap in the metal, I am screwing in the bracket screw to block the bracket from going below it, otherwise it would slide down much further.
I'm still tempted to add shrimp, but there is not a lot of water in there with all the wood.
