Hey everyone. Just bought a new clownfish to go with my other clownfish. They're both ocellaris, both same size. The first couple days I put the new one in, both clowns were interested in each other doing the little jiggly dance or whatever you call it. Seemed to be going great. There was an instance of one nipping the other but when I called my LFS they said to give it a couple weeks because the new one might be changing sex in order to be compatible with the other. It was the next day that the newest clown started hiding in one rock crevice and hardly comes out. It sticks its head out every once in a while but then goes back in. The other clown is swimming around just fine like nothings changed. Why is this happening?
