Two places that are dedicated to SHs:
http://www.syngnathid.org/
http://www.seahorse.org
Each has a forum for rearing fry. Good luck!
Oh, and depending on what species you have, you will have to either get a brine shrimp hatchery going or a rotifer set up going. The larger the SH, the smaller the fry and the smaller the fry food. I can't tell what species you have, but if they are H. kuda or similaryly sized SHs, you will need rotifers for the first 1-3 weeks. After that, they will need newly hatched bs for a few weeks.
