It appears to be encrusting / growing across an existing piece of rock. The photograph does not do it justice color-wise. It is a pale, almost liminous blue with a dusky rose contrast. At the point where it is growing the encrusting base appears to grow about 2 mm in front of the top, and it's a burgundy color with bright green flecking. The mouths are each in a hole about 2mm deep and surrounding by these two color whirls.
Being unsure of where to place it I have moved it three times .. it has accellerated in growth more in the place I presently have it, which is under the MHs but on a slant, so it's not receiving full exposure. It is is low - medium flow.
The tissues appear to be partially inflated, because when I lift it, it goes almost completely flat with a spiny whirly skeleton partially exposed. It also slimes a little.
Since it is about to over grow the small rock it's on .. it prompted me to figure out if I want it to growth over the main reef rock, or if I should isolate it .. hence the enquiry.
One thing ... once it got knocked of it's initial placement and fell upside down (coral side down) onto another piece of coral. When lifted (about 12 hours later) the other coral had completely bleached on the part that touched it ... and then bleached completely and died within 3 days. This coral remained fine ... I'm sure this is telling me something about it's stinging capability ...
