hey thanks guys! He is really doing quite well. He seemed a little stressed in the following days after introduction, but now he is well acclimated and active. He seems so big too since my other fish are small. There havent been any fights yet, but I am keeping my eye on him. He is also leaving my urchin and coral banded shrimp alone. The CBS thinks he owns the tank anyway, I dont think there will be a problem between the two.
