Good tank mates
This is a designer long-finned ocellaris clownfish, one of the more peaceful clowns, and it fits reef community tanks with gentle fish like firefish, gobies, cardinalfish, and small wrasses. It is reef-safe with corals and most invertebrates. Keep only one clownfish or a single bonded pair, since unpaired clowns fight, and avoid aggressive or fast-moving tankmates that could nip its trailing fins or outcompete this slower swimmer.
Good to know
Longfin Black Ice is a captive-bred designer ocellaris with three white bars over a dark body and flowing, extended fins produced through selective breeding.

Royal Gramma
Peaceful basslet that shelters in rock caves, occupying completely different territory than the anemone-tending clownfish. Multiple hobbyist threads and care guides confirm smooth coexistence with ocellaris pairs, including in tanks as small as 20 gallons. Not an Ecsenius-type fin-nipper; no predation or aggression risk toward clownfish.
Pajama Cardinalfish
Deeply peaceful, slow-moving fish with no aggression toward clownfish. AquariumSource and broader reef community consensus list cardinalfish as reliable ocellaris tankmates; the species occupies mid-water open-reef space with no territorial overlap.
Yellow Watchman Goby
Peaceful sand-bed dweller that stays on the tank floor, entirely separate from the clownfish's anemone territory. Reef community sources confirm it as peaceful in community reef systems with no predation risk in either direction.
- P
Purple Firefish
Timid, peaceful dartfish that hovers near the sand bed and does not compete with clownfish for territory. Confirmed compatible in reef community setups alongside ocellaris; it is more likely to be the bullied party than the bully, and ocellaris are too docile to harass it.
- C
Court Jester Goby
Peaceful toward all fish except conspecifics; no aggression, predation, or territory overlap with clownfish. Compatible in reef community tanks. Note: wild-caught specimens are notoriously poor prepared-food eaters and often starve — captive-bred (Biota) specimens are strongly preferred and adapt well to aquarium feeding.
