Sea Horses

Hi, I was wondering if anyone has any Seahorses in their aquarium. I have only had experience with Betas, algae eaters, gold fish & other common fish.
The other day, my brother found a dead sea horse on the sidewalk,randomly! I thought it was so cute. I kept it in a bag, I know I'm a weird-o!
I really love Seahorses & want to get atleast two.
Anyone have experience with these unique little cuties?

I posted some pictures below of the kind that I want:



Arent they so cute?!
