Had a question, if we decide to upgrade to a 180 or bigger in the next few months, transfer everything out but the heater zoanthid and mushroom and a small powerhead, 120 GPH or something. How many seahorse can go in this tank? Erectus seahorse I think they are. How many of those, more flow for the 46 gallon? Then are they safe with the 47 lbs live rock and just add some plastic plants or marine plants?
