I will be capturing 4 larger blue chromis this week and would offer them up to anyone that would like to add to an established tank. I have grown these from very small to 3-3.5". All four have been together over the last several years. They are ferocious eaters and are getting too big for some smaller fish I'm wanting to add. Would be great for a fish only tank or bigger reef tank. Prefer to keep them together but open to splitting them up. JP
