So I saw the 6 gallon nano cube, and I was wondering if in the future I should set it up as a seahorse tank. I would maybe put one H. Fuscus seahorse in, because I don't want to have to deal with the live food for dwarfs. On seahorsesource.com, it says that they need 15 gallons for one pair, but if I do just one seahorse, will it be okay? Do I need to do anything to the intake of the filtration, or are these seahorses to big for the water movement to hurt them? Will I need to diffuse the out put of the water from the sump? The tank dimentions are 11/11/13, I think. Thanks!
