I just added one to my nano, and planned for it to host a sexy shrimp or porcelain crab. Anyways the thing won't attach, he didn't bury his foot, nor will he attach to a rock. I did feed him (since he was in a tank with minimal light) He ate, then this morning spit out the food. Not really sure what he wants at this point. Im wondering if I should just bury the foot. I can't find any info on captive care so if anyone can help id appreciate it.
Heres a pic of him last night expelling the food. ( piece of fish flesh)
