Sub-tropical / cool water tank. This tank currently runs at about 69 degrees and I am hoping to drop it a little more yet. The angels are deep water angels and can not live in 78+ degree water long term. The wrasses are adjusted down to the cooler temps.
Then you use a chiller? Where do these fish come from with the cool temp? What else do you have/are getting?
Hope you don't mind all the questions, I find this very intriguing. Anything new and I wanna know about it
