Well thank you. I just love seahorses as well as the mythical hippocampus. Anyway, I wasn't aware I really needed more flow, but if I do, I'll get some. I plan on having some mushroom corals and maybe some small polyp corals. Example: the nano mushroom starter pack, and the nano polyp starter pack from LiveAquaria. i just looked into them and would the Koralia Nano 425gph work?
