i put them on the top of the rockwork and i hadnt seen much growth. then i find out that part of the "rock" they are on is actually some sort of clam. he made it to the bottom of the tank where there is very little light. and the polyps attached to it are doing great. however the majority of the polyps are mostly closed all of the time on the other pieces of rock. anyone have any experience with these corals?
they look like a mix of gsp and snowflake polyps
