Pipefish that come out of florida are a pretty good choice if you choose to go that direction. They do need to be fed mulitple times a day and are slower eaters than normal fish. Not as slow as seahorses, but close. They will eat frozen, but have "live" available when they arrive as they have to be trained to eat frozen. Hatching baby brine will be fine. Adult brine would be better. They are pretty cool and breed like rabbits. I have a few and I am very happy with them. I do have to keep them in a tank dedicated just to seahorses and pipefish.
