Alligator Pipefish Care Facts

Care Level: Expert
Temperament: Peaceful
Diet: Carnivore
Reef Safe: Yes
Minimum Tank Size: 100 gallons
Max Size: 12 inches
The Alligator Pipefish, Syngnathoides biaculeatus, exhibits a straight pencil-like body and is related to the Seahorse. Its slender green body features an elongated snout resembling a pipe giving it its name. They do not possess teeth and have specialized armor-like scales. The Alligator Pipefish uses its dorsal fin to swim around the tank although it is a weak swimmer that will spend much of its time floating. 
The Alligator Pipefish is peaceful, will eat a carnivorous diet, and can be housed with other members of its own species. They require a large tank with plenty of live rock, plants, and structures to grab onto. Seahorses and Pipefish can actually form a symbiotic relationship together as the Seahorse will grab onto the Pipefish. They are reef safe so long as they are not housed with aggressive corals, sea anemones, or aggressive inverts.

Beautiful, healthy specimens, readily taking frozen Mysis. These gentle giants are now the main attraction in my seahorse tank.

The Alligator Pipefish was shipped extremely well, and it was a perfect addition to my reef tank. I acclimated according to the instructions, and I have had no problems with any of the fish I have received. What more can you ask for? Cheaper then my local fish store and it was delivered to my front door the next day.
