how about learn the needs for them first, not to sound like a azz but seahorse are the one thing in the hobby i take a little more serious, it isnt they cant handle the flow, high flow makes it hard for them to capture food, a seahorse will kill off sps grabbing and holding it, as well as you cant put them with any lps that has feeder tenicles or stingers, they do best in 67-75 degree waters as this leaves them less succeptable to disease, if you want corals just get alot of zoa's, seafans and some leathers, anything else is not reccomended, and really dont suggest putting them in any tank less than 6 months old as they dont handle amonia, or nitrates or fluxes to the tank chemically. and lastly not to sound like a d+ck, but i know enough people with money that dont care about side effects but want instant gratification, and a seahorse tank isnt that type of system to do that with
