Edit: I thought haddoni's were blue; upon a quick live aquaria search it appears that what they are. They're big, there's two of them in one tank with a solo clarkii all by themselves. They want to move them so they can use the tank again lol. Look healthy, and have been there for a few months so they are in good health. Honestly would have brought one home today, I just don't have the real estate in my tanks. I have too many bta's now as it is!
