How we check: each species' minimum tank size against your display volume, plus quantities and behaviour pairings between tankmates.
Clownfish
Saddleback Clownfish
Amphiprion polymnus
The saddleback clownfish is a dark brown-to-black anemonefish marked by a white head bar and a distinctive incomplete white saddle across the mid-back, with yellowish fins and an orange-flushed face. Unlike most clowns it is a lagoon and sandflat species that partners with sand-anchored host anemones such as the carpet (Stichodactyla) and long-tentacle (Macrodactyla) anemones, so a fine sand bed suits it well. It is moderately territorial, best kept as a pair, and makes a hardy, characterful display fish.
