Hi
I have Helfrichi firefish that share a hole with pistol shrimp. Is that normal or any one have a same experience as mine?
In my tank I have blue tang, purple firefish, Helfrichi firefish, 2 clown fish, 2 goby, 2 angle fish.
OH and Helfrichi firefish, purple firefish and pistol shrimp are all share the same hole.
thanks
