The Longfin Clownfish B28 is a captive-bred longfin expression of Amphiprion ocellaris, carrying the familiar orange body and three white bars alongside dramatically elongated, tasseled fins that take on dark borders as the fish matures. The unusual finnage is a healthy trait rather than a deformity, and it does not interfere with normal swimming, feeding, or behavior. Adults reach roughly 3 inches, with females growing larger than males. The ancestral form ranges across the Indo-West Pacific, where it occupies shallow coral reefs and calm lagoons, frequently associated with host anemones.

Plan on a 30-gallon aquarium or larger for an adult pair, furnished with mature rockwork that offers hiding places and defensible territory along with open water for swimming. A host anemone is optional; captive-bred longfin ocellaris settle in and thrive without one, though they will often adopt an anemone if it is present. Many specimens also claim a coral, rock overhang, or other reef feature as a substitute home. Stable tropical conditions and consistent husbandry matter more than any specialized decor, and no unusual substrate requirement applies to this fish.

Ocellaris clownfish are omnivores that graze widely on the reef. Recorded natural foods include copepods, amphipods and other small crustaceans, polychaete worms, fish eggs and larvae, algae, and material derived from their host anemones. That mixed intake of animal and plant matter should be the model for captive feeding.

Tank-raised specimens are unfussy eaters and readily accept quality marine pellets and flakes, frozen mysis shrimp, and frozen brine shrimp, supplemented with herbivore or algae-based preparations to cover the vegetable portion of the diet. Offer a varied rotation in two to three small feedings each day rather than one heavy meal. Captive-bred fish typically begin feeding promptly after introduction, with no special acclimation feeding regimen required.

Ocellaris rank among the least combative clownfish and make calm, engaging display fish. They spend much of the day hovering and darting within a small home range, and an established individual or pair will defend the rockwork or anemone it has adopted. Distinct pairs are monogamous, with the larger of the two developing as the female. Once bonded, a pair tends to stay closely associated with its chosen site.

Choose peaceful community tankmates. Boisterous or fin-nipping species are poor company, since the trailing fins of this morph invite nipping damage. Exercise caution when adding additional clownfish, particularly after a pair has claimed a territory. The fish is reef safe and does not nip corals or clam mantles, and it presents no particular threat to ornamental shrimp, crabs, snails, or small fish, though territorial displays near a favored anemone or reef site should be expected.

FAQ

Frequently Asked Questions

About the Longfin Clownfish B28

  • Is the Longfin Clownfish B28 a separate species?
    No. The longfin form is Amphiprion ocellaris, and B28 functions as a specimen or inventory identifier rather than a recognized taxon.
  • Does this clownfish require a host anemone?
    No. Captive-bred longfin ocellaris thrive with or without an anemone, though they will often accept one when it is offered.
  • What tank size and feeding schedule suit an adult?
    House adults in at least a 30-gallon aquarium with rockwork and swimming space. Feed a varied omnivorous diet in two to three small meals each day.
