so a couple of days ago i decided to take the next step with my sw tank and get a coral. I went down to a trusted LFS and bought a little zoa frag with two types of zoas on it and about 5-10 polyps on it. i drip acclimated them for about 30min and set them high in the tank. despite what my profile says i now have downgraded to a biocube 29 with just original pc lights. The LFS keeps them under 400W metal halides which is why i started them on the top of the tank. After observing them for the last couple days the one type has never even opened one polyp and the other type has opened 1-3 during the day. is this normal for them to not open in the first couple days or should i be concerned? the water in the tank is from my original setup so prob about 2 years running with a fairly low bioload of 3 small fish. Any input would be apreciated. water tests show all normal so im kinda stumped on this my only theory is the light is to intense at the top of the tank so what should i do? Thanks in advance.
