That's great! When I was at the Mall of America in MN, Underwater Adventure had a great seahorse display too. The Como Zoo there had a Tanganyikan cichlid exhibit I loved!
From what I've read, they are close to being on the endangered species list and the regulations to keep even in public aquariums are super strict. I believe they are next to impossible to breed in captivity. Even if someone was to keep them in a private aquarium, good luck finding information on their living conditions and all that. I'd be just fine if they were left to the experts or nature to handle.
