Gobie and Shrimp Pair Question

[RCFA]

Mine seem to show up in a new hole every night around feeding time. Always out front. It is great to see the shrimp making the hole and I do have to target feed a bit as nothing really settles near them if I don't put the food right out in front of their hole. every day their old hole is closed up and they are back out the next night somewhere else. They must have a huge network of tunnels under my rock.

I was watching the world's most extreme animals and they had a section on the pistol shrimp. It explained how they hunt and how their strike is like a sonic weapon. They showed footage of it hunting, and it killed and ate a cleaner shrimp. I would have never thought they could live with other shrimp in an aquarium! I guess with lots of food present they have no need to kill anything else... that is so cool.

Mind you I keep a puffer, banana wrasse and a trigger with a coral banded, cleaner and peppermint shrimp and have had no losses as of yet.
