Often sold as the scooter blenny, the scooter dragonet actually belongs to the dragonet family (Callionymidae). Its brown mottled body is scattered with white and black spots that look like a sprinkling of stars, and males carry a tall, large first dorsal fin. It moves as if gliding across the sand. Reaching a maximum total length of 8.9 cm, it is calm in temperament, but it forages for tiny live food in the tank, so it is best suited to experienced keepers who enjoy patiently building a settled aquarium and watching their fish.

About Scooter dragonet
The scooter dragonet is a small, star-spotted marine fish that glides over the sand, reaching a maximum total length of 8.9 cm. Rated for experienced keepers. Key traits, care points and tips to know before bringing one home.
7 things to know before welcoming a Scooter dragonet
1Why it suits experts
This species is rated for experienced keepers. Both securing suitable food and keeping the tank environment stable call on prior experience. It is wise to get comfortable with basic marine fish care first.
2Start with a mature tank
It feeds daily on tiny crustaceans that live in live rock and sand, so a freshly set-up tank is a poor fit. Prepare a settled tank where such small creatures have had time to establish themselves.
3Food and feeding
The tiny creatures in the tank may not be enough on their own. Offer small amounts of frozen small crustaceans and watch whether it eats them. Whether an individual accepts prepared foods varies from fish to fish.
4Sand and hiding spots
This fish glides across the sand and tends to spend its time near the bottom. Fine sand and a rock layout with places to hide help it settle in. Avoid crowding the bottom with objects so it has room to move around.
5Tank mates and males
Its temperament is calm, so peaceful tank mates are the better match. Fast-feeding fish can make it hard for this species to get enough food, so choose companions carefully. Males may quarrel with one another, so think carefully before keeping more than one.
6Stable water and acclimation
Sudden changes in water quality or temperature put stress on fish. Acclimate it slowly when it arrives, then keep conditions steady with regular water changes and water checks. If you notice signs of poor health or are considering medication, it is reassuring to consult an experienced keeper or specialist.
7Planning for the long term
Data on its lifespan is scarce, and no clear estimate is known. Daily observation helps you notice changes in appetite or movement. As with other marine fish, it is reassuring to keep a lid on the tank in case of jumping.
Frequently asked questions about Scooter dragonet
- Q.Can a beginner keep one?

- Q.How large does it grow?
- A.The maximum total length is 8.9 cm (FishBase). It is small, but it moves around near the bottom searching for food, so leave some room in both the tank size and the rock layout.
- Q.What does it eat?
- A.It eats tiny crustaceans living in the sand and rock of the tank. Some individuals take frozen small crustaceans, but this varies from fish to fish. Get a settled tank and a feeding plan ready before bringing one home.
- Q.Can I keep more than one?
- A.Males may quarrel with each other, so consider it carefully. Males have a tall, large first dorsal fin, which helps in telling the sexes apart. Tank size and whether enough food reaches every fish are also worth weighing.
