Hi all, I’ve been running my Evo 13.5 for almost 2 months now. My Rainford’s Goby dug a lair out beneath part of my rock work and currently spends 95% of his time staring at me from inside. During one of our staring contests I noticed what looked like a smooth, ovular, egg-shaped thing with occasional pink bumps on it protruding from the sand. I have NO idea what it is. Here’s a picture. The green thing is his face poking out. It’s unfortunately the best picture I have been able to get... My tank is captive-bred only, as I was hoping to minimize any hitchhiking. Here’s what I’ve got: CaribSea Live Sand CaribSea LifeRock 2 ORA clowns 1 Biota Rainford’s Goby 1 Biota Green Finger Leather 1 Biota Ultra Green Polyp Leather 1 WWC Aquacultured Xenia Any ideas what the heck it could be? The Goby rubs up against it in an uncomfortable, he-should-probably-ask-permission sort of way. Here’s a pick of the whole tank, for fun. It looks like an alien is going to pop out of the thing, so thanks for all your help!
