I am using pennywort for foreground and will wrap around showpiece rock.
back corner will plant stem rotala colorata/rotund/ or butterfly.... I will have long stem so should be close to light. If this dies will go with lower light red crypt.
on right corner planting stem water sprite and java moss on small rocks holding showpiece rock in place.
All low light, with mineralized topsoil, and NO co2. I may dose with flourish excel (but may not be needed with my soil). Will take pictures of progress!!! Dwarf puffer breeding tank, 3 ottos, with cherry shrimp and ramshorn snails (for food).
