I have this section of my rock work the swoops down into a cave. Not a great spot for an SPS and I don't want anything that grows so tall (eg toadstool) that blocks the cave entrance. I like the movement of corals like frogspawn (already have) and Xenia (already have), but what would be a good option for a coral that encrusts and grows low to the ground but it's tentacles aren't super long. Also, no mushrooms. Thanks!
