They actually hang out next to thomas most of the time since he's in the cave.
If you have intense light, I wouldn't put the brain up there. The bottom of the coral will be fine, but with your current rock, I'd be more worried about it falling off. With as little rock you have it might be easier to move the rock your anemones are on. Of course they might move in their own after that. And yes they will sting other corals.thats not a bad idea...thanks!!! i'll try it
is there any issue with putting open brains that high and on live rock? not sure if their bottoms will be damaged?
also would the bta sting the brain? i'll obviously put it say an inch or two away
