I have a Mycedium robokaki frag that is acclimating on the bottom of my tank. I think it looks good, but don't really know what it should look like. So far I haven't seen any sweeper/tentacles. Don't even know if it has them. Does it eat? Do I feed it, when day/night, and what? I fully realize I should have answered these questions before getting it. I plan to mount it vertically on a rock about mid-way up in the tank. Can't control my impulses.
