Suitable for a tank as small as 10 gallons, the colorful and peaceful court jester goby (Koumansetta rainfordi) is perfect for many marine nano-tanks. They have been documented eating red cyanobacteria. These captive bred specimens are much hardier and easier to feed than wild individuals.

Description

Court Jester Goby (Koumansetta rainfordi)

The court jester goby (also known as Rainford’s goby) is an attractive little fish that is suitable for any nano- or large-scale marine aquaria. In fact, they’re fairly social and get along well in small groups when housed together in larger tanks. These fish are known (and appreciated) for their habit of nibbling on hair algae. Wild caught court jesters can sometime have a difficult time adjusting to aquarium life, particularly because of their tendency to refuse prepared foods. They often are shy when first introduced to the aquarium and can become targets to aggressive tankmates. They are much easier to feed, as they usually accept items such as small pellets, frozen mysis shrimp, brine shrimp, etc. See below for more information.

Size and Care Requirements

  • Purchase Size: ~2″ (length)
  • Max Size: 3″ (length)
  • Water Parameters:~78° F, dKH 8-12, pH 8.0-8.4, s.g. 1.021-1.023
  • Color: Green and orange stripes with black and white spots
  • Reef-Safe: Yes
  • Feeding: Omnivorous

Species Information

Koumansetta rainfordi occurs in Western Pacific Ocean coral reefs. This smallish, wary fish prefers water depths of 2-30 m (6.6 to 98.4 ft).

Benefits of Aquacultured Marine Aquarium Livestock

Aquacultured fishes offer a huge advantage over wild-caught specimens. For example, when bred and raised under captive conditions, they adjust more easily to aquarium life. They are also less likely to carry disease. Even more, aquacultured specimens can better tolerate shipping stress. Most notably, by purchasing aquacultured fish you support the aquaculture of marine organisms and help to make our hobby more sustainable!

100% Alive on Arrival (AoA) Guarantee

We guarantee that every court jester goby we sell will be Alive On Arrival and in good health. Should it arrive in any other state, we will either replace it free of charge (including shipping) or issue store credit if the total livestock loss is less than $40. For more information, please also visit our 100% Alive On Arrival Guarantee page.

  1. Rated 5 out of 5

    Charlie (verified owner) – April 11, 2020

    Love this little fish. He is a very peaceful tank mate. Best friends with my yellow coris. He eats a little of everything like gha,mysis,brine and even prepared foods. He is a sand sifter too. You can’t go wrong with this fish.

  2. Rated 5 out of 5

    James Wohler (verified owner) – April 28, 2020

    Nice fish, good sized and very healthy on arrival.

  3. Rated 5 out of 5

    James Wohler (verified owner) – May 1, 2020

    Very nice fish healthy as can be. Calm and good for a gentle tank.

  4. Rated 5 out of 5

    Chris Dunbar (verified owner) – December 18, 2020

    My family and I are really enjoying this little fella. It took him a couple of days to settle in and start eating. You could tell he was curious about what the other fish were eating, but couldn’t quite figure out what he wanted. Despite spending a ton of money on fancy frozen foods and live artemia, in the end he was happiest with TDO pellets and some flake food I “borrowed” from my son’s guppy tank. The description says they can be kept together, and I am thinking about adding a second one.
