Pipefish and SeaHorses are in the same category. they req special diet, multiple feedings daily, Prestine water conditions, special tank setup including lots of hiding places, hold fasts, algae, no sharp edges, and very low flow. You wont be able to keep much else in a tank with Pipefish/seahorses. They are not for new aquariust. I have wanted to keep them too, but with my work schedule, i'd never be able to properly care for them. Whatever animals you decide to keep, be sure to do research first, which includes asking questions here.
