That looks pretty close,eh!? I have one in my tank, it came on some Brazil rock. It's been there for about 3 years or so, it dwells in a cave created by encrusting and plating corals and doesn't harm a thing(that I care about anyway:wink:), it's about the size of a toonie now. You're welcome, anytime!

I have the same thing but its growing on the back of one of my snails and its very pink, other than the colour it looks identical.
I was just asking my wife what she thought it was and was coming on here to see if I could find anything on it ... lol

That's too funny....coincidence?...I think not! They do come in pink too!
