Hey all! New to the forum, and semi-new to the hobby. I kept a tank long ago with my Dad and have recently gotten back into it. I'm mostly a freshwater guy, but really wanted a reef again. I've got a 10 gallon nano that was doing well with some brain coral, mushrooms, shrimp, and a solid cleanup crew. I wanted a zoa colony, so I picked out a nice, small one at my LFS. I started the zoas on the sandbed, but they started reaching pretty heavily, so I moved them up (thinking they wanted more light). Now, though, they're starting to lose color and I'm not sure what else they might want. Tank parameters are all pretty solid -- no detectable phosphate, good calcium level, etc. Any help or input would be appreciated! Please see pics below FWIW -- Light is a current LED bar with ramp up timer. Nothing too fancy -- it's the smallest size. Edit: I should mention -- they are growing new polyps, which is the strange part to me. I'd think if they were severely unhappy they wouldn't be doing that. I haven't kept zoas before though.
