Hello Reef Central! I am currently wondering for my new reef aquarium about symbiotic relationships. I already have clownfish and nems together, and I have heard about pistol shrimps pairing with gobies to make burrows... This is really fascinating to me, but which types of gobies will pair with pistol shrimp? Do they all pair? Is the pairing process guaranteed? My tank is peaceful and I plan on getting a cleaner shrimp eventually as well, would that cause problems with the pistol shrimp? Sorry for so many questions, hopefully, some of you guys can share some insight! Thank you.
