I just added second yellow, and him & my Kole sleep, swim, eat together.
So much so, ny wife has a new fascination with the tank. Takes video and pics of the two.
I kept an eye on my two after adding the Scopus, for about 2 hours to make sure they wouldn't be any fighting. I was worried but was hoping for the best, lol. They buddied up pretty quick. I've had a Royal Gramma for about 6 weeks and he's just now getting comfortable around the yellow tang. He could care less about the Scopus , but he's scared of the yellow tang
