Wheelers goby pair with shrimp

[las]

I have these guys coming in a couple days. I was wondering if anyone who has kept them could let me know best care for them.

One immediate question I have is about a crab that I have in the tank. I have a crab that came with a sponge I purchased. It’s the size of knickel. Any idea if any of these 3 guys are vulnerable to getting eaten by the crab?

Is the insert in the photo the 'crab' you have? Because that is a coral banded shrimp, not a crab and it would not be an issue for the fish.

If that's not your crab, we'd need to know what kind of crab you have. Some are very safe, some are kind of safe and some are serious problems.

It was a mithrax crab. He’s gone

I have a Wheeler Goby and candy cane pistol shrimp.

It took many weeks before I saw the Goby regularly during the day. Mine likes any meaty foods. The pistol shrimp mostly hides, but I have seen it sneak out to snatch some food and zip back into its tunnels.

About the only other care consideration is a decent amount of sand and a stable aquascape.
