Well since this topic has come up, I'm gonna give a shameless plug here so bear with me.
If you are up to a small amount of reading get a copy of "Workin Notes: A guide to seahorse diseases".
It was put together by my fellow members over at Seahorse.org.
You can get by following the link below or I belive it can be purchased through SeahorseSource.com also.
