At a glance the quick version
Looks how to spot one
Small scaleless dragonet
A flat little bottom-dweller that looks diamond-shaped from above, mottled in red, tan, brown and white with stripes or spots. Males are brighter and raise a tall, sail-like dorsal fin with an orange base.23
Personality what they are like
Peaceful and mild-mannered toward other fish.3
Daily activity how busy a day looks
Scoots across sand and rock all day, sifting the bottom for tiny food.3
Grooming and care the hands-on bits
Needs a well-established reef tank with live sand and live rock that supports plenty of copepods. Supplement with finely cut meaty foods and enriched brine shrimp.32
Home where they are happiest
Minimum about 30 US gallons (114 L) with live sand and live rock. Saltwater at about 22 to 26 °C, pH 8.1 to 8.4, dKH 8 to 12, specific gravity 1.020 to 1.025. Wild fish live on sandy lagoon and seaward reefs, rubble, algal turf and tidepools at 1 to 30 m.31
Food basics what goes in the bowl
Carnivore that lives mostly on copepods and other small bottom invertebrates. In aquariums it can be trained to take frozen or prepared foods.21
Company who they like around
Forms loose groups in the wild. Several can share a tank if added together, ideally two or three females per male.123
The story where it all began
Peter Simon Pallas described it in 1770 as Callionymus ocellatus. It is now placed in Synchiropus or Neosynchiropus, depending on the authority.2

Owner questions the things everyone asks
How often should I feed my Scooter Dragonet?
Furry Diary's starting plan is to offer small amounts once or twice a day. Since they constantly sift the sand for tiny food, a well-established tank with live copepods is essential. Supplement with finely cut meaty foods and enriched brine shrimp, but always check with a vet for exact amounts.32 Pet Wiki plan
What does a Scooter Dragonet eat, and what should it never eat?
This carnivore mainly eats copepods and small bottom invertebrates from live sand and rock. It can be trained to take frozen or prepared foods, but never feed it large or dry foods it cannot handle. Always ask a vet or good breeder for a safe diet list.321
How much space does a Scooter Dragonet need?
A minimum of about 30 US gallons (114 L) is recommended, with live sand and live rock for grazing. This gives them room to scoot across the bottom all day. More space is better if keeping a group.31
What temperature, light or water does a Scooter Dragonet need?
Keep saltwater at 22 to 26 °C, pH 8.1 to 8.4, dKH 8 to 12, and specific gravity 1.020 to 1.025. They need a well-established reef tank with live sand and rock. Furry Diary suggests checking temperature daily and salinity weekly.31 Pet Wiki plan
How often should I clean a Scooter Dragonet's home?
Furry Diary's plan includes a weekly glass clean and water test, plus a 10 to 20% water change every two weeks. Top up evaporation daily with fresh RO water, not salt water. Always follow your tank's needs and ask a vet if unsure. Pet Wiki plan
Can a Scooter Dragonet live with others?
Yes, they are peaceful and mild-mannered toward other fish. In the wild they form loose groups, so several can share a tank if added together, ideally two or three females per male. Always introduce them carefully to avoid stress.321
How long does a Scooter Dragonet live?
Lifespan varies depending on care and tank conditions. With a proper diet and stable environment, they can live for several years. For a more precise estimate, ask a vet or good breeder.
Can I handle a Scooter Dragonet?
It is best not to handle them, as they are small, scaleless bottom-dwellers that can be easily stressed or injured. Enjoy watching them scoot across the sand and rock instead. Always use a container if you must move them.32
