The Crocodile Pipefish are variable in colour from a green/yellow to brown or grey, depending on habitat. This species has a prehensile tial, which it uses to hold onto plant material, and no caudal fin.

They are usually found in protected coastal shallows over or among algae, seagrasses, or floating weeds.

The Crocodile Pipefish normally prefers to eat only live mysis, brine shrimp or feeder shrimp in a mature reef aquarium with plenty of live rock or macroalgae. An ideal diet to start this fish on is Live Copepods, and vitamin-enriched live baby brine shrimp, however, live baby brine should not make up the majority of its diet. Over time, the Crocodile Pipefish may become accustomed to eating frozen mysis and brine shrimp.

After an elaborate courtship dance, the female will attach her adhesive eggs to the flat area on the underside of the male's trunk. A pair will regularly mate in an aquarium if well-fed. It is not easy to determine gender, but mature males typically have a flattened appearance due to the brood patch, while females are more round. 

This social species is best kept in mated pairs or groups of its own kind in an aquarium. It may be kept with small, shy fish such as small gobies, seahorses, dragonets, and firefish. Aggressive, territorial, or fast-moving fish do not make good companions. Pipefish will be harmed by anemones and corals with stinging tentacles or corals that are large enough to consume them, such as brain corals. Pipefish can also be harmed by invertebrates such as crabs and large shrimp.
