I have built a 60f which has a fair bit of rock sticking out from the waterline (about 15cm x 20cm to be exact). Its dragon rock so there is lots of crevices. Which plants would do well under these conditions? I might be able to put some substrate in areas. Have tried MC, but it starts rotting after a while. Oh and the light intensity is at 100% (1900 lumen RGB light). In other words, these plants should love the light. Any ideas?
