Difficult to tell but my guess would be if it is loosing it's bright coloration that it is not doing so well...just a thought.

Sponges are pretty delicate and best left to develop, grow and thrive on their own. We have many sponges in our reef, white and yellow ones, but they just grew out on their own. I think sponges are best left for this type of life.

It is almost impossible to identify sponges visually. Take a look at this article. It does provide information on how sponges are classified and identified, but also includes some tips on their care.
