what the... my iTouch went NUTS! :lol:
The little cone snails are not on the Crocea at all -- or at least nowhere I can see. I've only seen them near the sandbed, on an old snail shell or the glass. The baby Turbos were all over the rocks in a certain area, I'm guessing where I assume they had hatched.
Some updated photos...
The new areas of growth on the RBTA, where it had lost the majority of its tissue/tentacles to the Koralia are growing back wonderfully... they're the beautiful bubbled tentacles.. too bad the whole nem doesn't decide to bubble up!! She looks kind of undecided. :lol:
In these pics she is starting to shrink down and get ready for bed. She is expanded to about the size of a small dinner plate at the peak of the day, right in front of the right side of the tank, covering the sandbed in that corner. I guess she figured out how to position herself as the showpiece in the tank!
The female Dispar has really improved and thickened up. She was very "ribby" before, now she looks nice and healthy.

She is a nice yellowey orange color with a yellow tail, the male is a dark orangey-pink with a bright red/magenta dorsal fin and pink tail.
The Crocea doesn't appear to be stressed, as the article Marc posted suggests Tridacnids look like when being sucked on by those nasty snails.
