Rykna, I know you have been struggling with Valiant for quite some time. Formalin can be extremely dangerous, and if not administered in the right dosage..it will kill your fish. If I were you, I would try to take this one step further than any forum and get on the phone. Seriously, there are places..aquariums, research facilities{such as MOTE in Sarasota FL} that do have seahorses since they are found around these waters. That's who I would talk to. Good luck.
