Yellow Clown Gobies question

[dekay]

Just want to let you guys know I'm a proud owner of a YCG since last night. Of all places, I got it from Big Als. It was held captive in a 3 inch cubicle which was pretty sad; housed with another goby and a shrimp similar to the pic above. So I decided to save the poor thing. Right now it's hiding in a cave I built, not sure if he ate any of the brine shrimp this morning though. But I made sure he had a meal, or was eating, before I took him home
