A "Designer Pair" of Amphiprion ocellaris, also known as clownfish, refers to a specific type of clownfish that has been selectively bred for unique color and pattern variations. These variations, Salvador Dali, Black Ice Snowflakes, or Snow Storms, are not naturally occurring and are the result of controlled breeding programs. These pairs are sold as a bonded unit, meaning they are two fish that the breeders have observed together and are likely to live harmoniously.
Here's a breakdown:
Selective Breeding:
Designer clownfish are the result of breeding programs that aim to produce specific color and pattern variations in the common Ocellaris clownfish.
Examples:
Black Storms are known for their black body with irregular white markings. Black Ice Snowflake clownfish are a cross between a Black Ocellaris and a Snowflake, exhibiting both black and snowflake-like patterns. Snow Storms are a result of breeding Black Storms and Black Snowflakes, displaying black fins, icy blue edges, and unique facial patterns.
Pairing:
Buying a "Designer Pair" ensures that the fish are likely to be compatible and not exhibit aggression towards each other, unlike randomly selected individual fish.
Reef Compatibility:
These designer clownfish are generally reef compatible, meaning they can be kept in a reef aquarium with corals and other invertebrates.
Symbiotic Relationship:
Clownfish are known for their symbiotic relationship with anemones, and designer strains, like their wild counterparts, can be housed with anemones like Bubble Tip anemones.
Captive Bred:
These fish are captive-bred, meaning they are raised in controlled environments, which often makes them more adaptable to aquarium life and less susceptible to diseases compared to wild-caught specimens.
