I currently have a 120G reef tank with a 40G sump/refugium. My next extension is a 30G macro algae refugium. After that, I was thinking about plumbing in a 50G tank to this system (36"x19"x19") to house some interesting non-reef safe species specific livestock. My plan was to make this more of a FOWLR tank. Originally, I was thinking puffer fish or something like that, but what about couple of S. Bandensis? The main issue I was wondering about is what happens if they ink? I would obviously have their filtration go straight into the skimmer, but do I risk killing the rest of the tank?
