Hi I recently purchased a piece of live rock which had coral, sponges and lots of other life on them. When I hit the blue lights I noticed this coral was glowing green. I've searched all over the net and am thinking this may be closed brain coral?
I have a
FOWLR tank and was wondering if this would survive? I have it placed high up to the surface, is this the best placement for these and should I use a lot of lighting now on?
Also out of the rock came this starfish. Does anyone know what type this is?
Many thanks in advance 😊
