Hey all, I bought a frag of galaxia about 3 weeks ago and so far it looks like its starting to grow some new polyps around the edges. however, i've noticed over the last couple of days that some of the polyps in the middle of the piece have started to retract and look like they are not happy. What kind of flow and light do they prefer? I had them about 3/4 of the way up in the tank(29g) and they are under a tek t5 fixture. Should I move them to the sand to see how they do there? Anybody who's had success with these corals please tell me how you did it. Thanks
