seahorses need to be fed live food i think, and i am pretty sure they need to be fed often. i have also heard they are very advanced fish, hard to get a hold of, and hard to keep alive... so you might want to do research. im not sure what everyones imfatuation (sp) is with seahorses, nemos, and dorys is, but it gets on my nerves. sorry if i crushed anyones hopes and dreams.
