Thanks for the feedback. Any special requirements for it? Preference for high or low light etc?

It actually expands quite a bit at times, then shrinks when there's something nearby (i.e. snail, shrimp)

If you look to the top right corner in the background, that looks like a dead plate coral too.

You don't really need to do anything at this point. You could feed it a pellet or some brine shrimp once a week. It is a very slow eater so make sure nothing steals the food from it.
