[phishin06]

Hi all!

I got a new tank set up and there is a hole a bit smaller than a dime hosting something that has been spitting ooze(white and grey) and getting dust all over the back of some Zoa's. I have been reading alot of different things because I havent been able to see it but today he has finally come almost out of the hole and let me take a few pics! Its not the easiest thing to see but I am hoping you pro's can help. Thanks for reading!

Trying to attach pics but they wont upload!

Everytime I try to load, it says error loading. Is the site having issues?

Has legs and is greyish in color with what appears to be big front arms. So frustrating it wont let me upload any normal pictures!

Gall crab perhaps? (just a shot in the dark)

Squat lobster? Just a guess since there's no pics.
