The pipefish, if caught on the Atlantic coast of Florida where the seller is located will most likely be Syngnathus louisianae (long snout) or S. scovelli (shorter snout). Both are nice fish. If caught on the Gulf side then scovelli or S. floridae. S carribaeus is very rare along the coasts of Florida (occasionally found as strays or in the keys but is mostly found around tropical islands), but because the morphology for many species in the genus Syngnathus are very similar, they are often all referred to as "Carribean" pipefish. If you buy some and post pics I can ID it for you. Good luck. Also, Syngnathus are usually pretty easy to convert over to frozen mysis (easier then wild caught seahorses for sure).
