I'm looking for culprits at this point, I didn't even find the body. He's not in the filter, or the carpet, I'm pretty sure he didn't go carpet surfing. It was a steinitz goby. His fellow inhabitants, Tiger Pistol shrimp, fridmani dottyback, and skunk cleaner shrimp didn't have anything to say about it. Is it possible the commensal tiger pistol ate him? or maybe his burrow caved in on him? This happened over the weekend when i was gone for two days...
