Pistol Shrimp or Crab Eat Goby?

[T-MIKE]

Hi,

I had a Strawberry Crab and went and got a Pistol Shrimp and Wheeler’a Goby. They were already paired up at the lfs. The only other fishes is the tank are two Pink Skunk Clownfish. The next day, I could not find the Goby anymore but I noticed the Strawberry Crab takes over the Pistol Shrimps home from time to time. One of my clownfish also bullies the Pistol Shrimp when it leaves its cave. I cleaned the tank today and lifted all the rocks and dug in the sand but could not find the Goby. Could the crab or shrimp had eaten it? I also searched around the tank 3 times and checked the filters but could not find it.

Highly unlikely for the crab to kill the goby. How big is the tank

5 gallons. I wonder if it can hide under the sand? I dug around the whole tank but didn’t find anything.
