Hi there, I have a 55 gallon fish only tank with a 1” ocellaris clownfish, algae blenny about two inches long, 5 hermit crabs, 2 nerite snails, and one turbo. The blenny and clown were purchased together about two months ago along with the hermits and snails. They all get along well but the blenny does pushups and challenges his reflection a lot. I added a small yellow watchman today and he is chasing him and trying to nip at him. The goby doesn’t seem to be too bothered as he keeps coming out and swimming around. My question is, if I get a pistol shrimp would that help the situation in any way or is the whole thing just a bad idea? Do you think the blenny will eventually leave the goby alone regardless? Thanks for reading
