Plan for rest of layout.
I want to do a smallish crypt carpet, maybe nevilli. Then attach some needle leaf java fern to the larger rocks at either end. Substrate will be gravel with an enriched/worm casting underlayer.
I don't know if I should try to slope the gravel up in the corners and continue the carpet up there or maybe find something for an accent plant or a taller leaning over type plant in the back and leave the rocks bare?
I will not be running CO2. Filter will be a hob, some kind of hardware store light for a low light tank.
For fauna, I will probably do something that doesnt mind room temps 68-70F. I am thinking of bloodfin tetras, WCMM, maybe neons, plus a small herd of RCS?
