I am not very good at IDing seahorses. These were taken at Puerto Gallera, Philippines.
I think this one is H. barbouri
I am not sure about this one
I also saw both pink and yellow color morphs of pygmies (H. bargibanti) on a single dive. They are posted at http://www.flickr.com/photos/drsteve
First one is: Thorny Seahorse, Hippocampus histrix
Second is Hippocampus kuda

Thanks Marli,
I thought the first one might have been a Histrix, but the guidebook said that they didn't have bands on their snout.
Here's one with the stripes from Lembeh; it's listed as a variation in Reef Fish ID (Allen, Steen et al). It better be a H. histrix, as it's being used as ID signage in a Bangkok Aquarium.
