The Orchid Dottyback, or Fridman’s Dottyback, is a marine fish in the Pseudochromidae family, which contains all the Dottybacks.
They are known scientifically as Pseudochromis fridmani, which is a reference to David Fridman, who first discovered the species.
These fish are endemic to the Red Sea, where they live up to 200 feet deep on reefs. They hide in small cracks and caves formed by rocks and corals.
Most specimens in the aquarium trade are captive bred and could cost from $30 to $60, so make sure you check that the fish are healthy before purchasing.
They should live between 5 and 7 years in a stable environment. Though there are easier marine fish to care for, beginners will be able to look after Orchid Dottybacks if they have done their research.
When first added to the tank, these fish will be shy, hiding away between rocks. Over time they will become more confident and even aggressive when they feel they need to defend their territory.
By providing lots of hiding spots, aggressive displays will be infrequent.
Most of the time Orchid Dottybacks will stay close to the decorations in the tank, rarely venturing to the surface except at feeding times.
Orchid Dottybacks stand out in any aquarium with their intense purple coloration. It covers their entire body and all their fins.
Some individuals are fringed with red on the top and bottom of their bodies.
The only other notable feature is a short black stripe that runs from their mouth back through their eye.
Their body is thin and long, though they only reach a maximum size of 3 inches. Their dorsal fin runs from just behind their head to their tail.
Sexing these fish is very difficult by eye.
Orchid Dottybacks are very attractive and sure to bring plenty of color to your aquarium.
Habitat and Tank Conditions
Wild Orchid Dottybacks are only found in the Red Sea. They live on reefs, spending most of their time in or around rock formations, which offer lots of shelters.
To create the perfect aquarium, you must replicate their natural habitat as best as you can. This is easy to do since their needs match many other popular saltwater fish.
Start with a fine-grained layer of sandy substrate or crushed coral.
You can then use live rocks to create a series of caves and crevices for these fish to swim around. They may offer great shelter and provide a territory for them to claim.
Having lots of caves in your aquarium is key to minimizing aggression.
You can have corals in the tank too, Orchid Dottybacks will leave them alone.
Maintain a temperature of 74°F-82°F, a pH of 8.1-8.4, and a specific gravity of 1.020-1.025.
The water should have a slight current and be moderately lit.
What Size Aquarium do they need?
This species is small, but they need enough space to claim a territory and not have to defend it all the time. A 30-gallon tank is recommended, but bigger tanks are always better.
Orchid Dottybacks can be aggressive and territorial when other fish get too close for comfort, but this shouldn’t be a problem in a large tank with many hiding spots.
Tankmates should not be timid though, so they can defend themselves if an angry Orchid Dottyback comes their way.
You should take note of how big any tank mates will grow. Orchid Dottybacks are only 3 inches and could easily be eaten by larger fish like a Lionfish.
These fish are considered reef safe; they won’t damage your corals.
Can You Keep Orchid Dottybacks Together?
Keeping Orchid Dottybacks together will increase the risk of fighting.
It is safest to keep them singly, but they can be kept in pairs if the tank is large enough with lots of separate caves throughout.
You can feed Orchid Dottybacks most foods. They are primarily carnivorous, but they will eat whatever they come across.
You could provide some dried foods like flakes and pellets, but these are never as nutritious as live/frozen foods. Try giving them brine shrimp, Mysis shrimp, and other chopped meaty foods.
Varying the diet when you can is the best option; they’ll receive a variety of nutrients. This helps to maintain vibrant colors too.
Feed your fish 2-3 times a day.
Day-to-day care of Orchid Dottybacks is easy. They just need a healthy diet and a well-maintained aquarium, which is always important for aquarium pets.
Keep the tank clean and perform regular partial water changes. Use a water testing kit each week so you can spot any unwanted changes in the water parameters and soon as possible.
Common saltwater diseases are a possibility with Orchid Dottybacks, but they aren’t particularly prone to picking them up. Disease should be rare in a clean aquarium.
If you do notice that something is wrong then separate the infected fish in a quarantine tank for treatment, only returning them once treatment is complete.
Captive breeding is becoming more common and lots of aquarists are now having success at home. Most Orchid Dottybacks on sale are now captive bred which has reduced their price.
If you have a pair, then spawning should happen regularly in a healthy aquarium. You will need to maintain the perfect water conditions and supply a highly nutritious diet.
The male will court the female. If accepted, the female will deposit her eggs in the male’s territory for him to fertilize.
The male will care for the eggs until they hatch to release larvae after 4-5 days. At this point, separate the parents and raise the young on their own.
Are Orchid Dottybacks Suitable for Your Aquarium?
If your favorite color is purple, then Orchid Dottybacks are perfect for you, though everyone can enjoy their majestic purple color.
