At a glance the quick version
Looks how to spot one
Slender, elongated dottyback
A slim little fish in a vivid orchid purple, often with a darker streak running through the eye. Its body is long and narrow, ideal for slipping into small holes in the reef.23
Personality what they are like
Full of personality. It can be a little shy at first, then becomes a bold, curious resident that keeps an eye on its chosen hiding hole and may chase smaller fish away from it.2
Daily activity how busy a day looks
Starts out hanging close to its shelter and swims more openly around the rockwork once it feels at home.2
Grooming and care the hands-on bits
Give it plenty of small holes and ledges in the rockwork and add it to the tank alongside other dottybacks rather than after them.2
Home where they are happiest
Minimum about 30 US gallons (114 L) with rockwork full of crevices. Saltwater at about 22 to 26 °C (72 to 78 °F), pH 8.1 to 8.4, dKH 8 to 12, specific gravity 1.020 to 1.025.2
Food basics what goes in the bowl
Carnivore. Wild fish hunt zooplankton near ledges; in the aquarium offer a varied mix of meaty foods.21
Company who they like around
Usually kept singly; can share a tank with other dottybacks if they are introduced at the same time.2
The story where it all began
Wolfgang Klausewitz described the species in 1968 and named it after David Fridman of the Maritime Museum in Eilat, Israel, who collected the type specimen. It has since been bred in captivity and is a popular reef aquarium fish.3

Owner questions the things everyone asks
How often should I feed my Orchid Dottyback?
Feed your Orchid Dottyback small amounts once or twice a day. Furry Diary's starting plan suggests daily feeding, but always check the food label and ask your vet for exact portions.2 Pet Wiki plan
What does an Orchid Dottyback eat, and what should it never eat?
This carnivore enjoys a varied mix of meaty foods like zooplankton. Never feed it anything that isn't meaty or appropriate for saltwater fish; a vet can advise on safe options.21
How much space does an Orchid Dottyback need?
It needs a minimum of about 30 US gallons (114 liters) with rockwork full of crevices. This gives it room to explore and hide.2
What temperature, light or water does an Orchid Dottyback need?
Keep saltwater at 22 to 26 °C (72 to 78 °F), pH 8.1 to 8.4, dKH 8 to 12, and specific gravity 1.020 to 1.025. Furry Diary's plan includes daily temperature checks and weekly salinity tests.2 Pet Wiki plan
How often should I clean an Orchid Dottyback's home?
Furry Diary's plan suggests a weekly glass cleaning and a 10 to 20% water change every two weeks. Also top up evaporation daily with fresh RO water. Pet Wiki plan
Can an Orchid Dottyback live with others?
It is usually kept singly, but can share a tank with other dottybacks if introduced at the same time. It may chase smaller fish away from its hiding hole.2
How long does an Orchid Dottyback live?
Lifespan varies depending on care and environment; ask a good breeder or exotic-pet vet for specific expectations.
Can I handle an Orchid Dottyback?
It's best not to handle this fish; it is delicate and needs its water home. Enjoy watching its bold, curious personality from outside the tank.2
