Can beginners keep it?

It is rated beginner-friendly. However, it grows up to 16 cm and can become territorial, so think about tank size and tank mates before you buy.

Can it live without an anemone?

In the wild it lives only in Haddon's carpet anemone, but in an aquarium it can often be kept without one. An anemone needs care of its own, so it may be easier to consider one after you have gained some experience.

It reaches up to 16 cm in total length, which is large for the genus (FishBase). Juveniles are small, so choose a tank with the adult size in mind.

How long does it live?

There is little reliable information on its lifespan, so no firm figure can be given. Plan for a long-term commitment and keep it in a stable, well-maintained tank.

Can it share a tank with other clownfish?

Because it can become territorial, it is safer not to mix it with other clownfish species. If you want a pair of the same species, bring home smaller fish together, provide hiding places, and watch their behavior.

Sebae anemonefish

About Sebae anemonefish

Sebae anemonefish: an Indian Ocean clownfish with a dark body, two white bands and a yellow tail, up to 16 cm long. Beginner-friendly, with tips to know before you buy.

7 things to know before welcoming a Sebae anemonefish

1A Larger Clownfish
It reaches up to 16 cm, which is large for a clownfish. Juveniles look small, but plan a tank with plenty of water volume for the adult size. Cramped tanks make territorial disputes and water quality problems more likely.
2About Host Anemones
In the wild it lives only in Haddon's carpet anemone, but in an aquarium it can often be kept without any anemone. If you add one, the anemone needs its own care for lighting and water quality. Starting with the fish alone is a reasonable way to get used to the setup.
3Territory and Tank Mates
As it grows, it may defend its territory against its own species and other clownfish, so mixing clownfish species is best avoided. With other fish, rockwork and hiding places that break lines of sight help reduce conflicts. Watch how everyone behaves after introductions.
4Pairing and Sex Change
Clownfish change sex as they grow, and the largest fish in a group becomes the female. To form a pair, a common approach is to bring home smaller individuals together and let them pair up naturally. If you want fish that are already paired, ask the seller first.
5Water and Acclimation
Marine fish are sensitive to sudden shifts in temperature and salinity, so acclimate the fish slowly after it arrives. It is rated beginner-friendly, but it is safer to add it to a tank that is already established and biologically stable rather than a brand-new one.
6Health Checks on Arrival
After arrival, check every day for white spots on the body, damaged fins, fast breathing and appetite. Quarantining the fish in a separate tank for a while makes it easier to avoid bringing illness into your main aquarium.
7Feeding Basics
It is an omnivore and accepts prepared foods and frozen foods. Feed small portions a few times a day rather than one large meal, and remove leftovers promptly. When buying from a breeder, ask in advance what the fish is currently eating so the transition goes smoothly.
