Tailless Ocellaris Clownfish


Some oddities of the sea, like the Picasso clownfish and Lightning Maroon clownfish turn out to be stunning. Others seem to be completely pointless, much like the pair of clownfish in the above video. These tailless Ocellaris clownfish seem almost normal, except they are lacking a tail. Each fish in the above pair has a caudal fin (the fin typically located at the end of the tail), but the structure leading to this fin is almost completely gone. In it’s place is a nub.


Apparently, the origination of these fish is somewhat of a mystery. The YouTube user who uploaded this video claims the fish to a natural, wild-caught clownfish. Others, say otherwise, indicating that these weird clownfish are in fact normal clownfish that had their tails surgically removed. Regardless of how these fish came about, they seem very pointless. Special thanks to AquaNerd commenter “Narwhal” for pointing out that these fish aren’t natural, but are commonly cut on to drive up their prices. We’ll dig a little deeper and find out who is cutting these fish and for what point (if not commercial).

    I saw this in another blog post a couple of weeks ago. These fish are not wild caught. They had their caudal peduncle removed surgically. These fish are located in a store in Singapore which is an area infamous for this kind of cosmetic mutilation (Blood Parrot cichlid anyone?). Someone is just trying to pull a fast one claiming they are wild caught in order to drive up the price so they can make some money.

    • thanks for the update narwhal. i honestly had my doubts as to the fish being naturally tailless, but i just went with the information that was given to me. do you have any source for what you are saying? i'm not doubting you, just curious.

    I saw the story first on Glassboxdesign. Not sure if that is the originator or not. But in that story they give the location of the fish (Singapore) and considering the location and the preponderance of cosmetically mutilated fish originating from that area it makes the most sense. If you consider that the mathematical odds of finding TWO fish of the same age with the same deformity at the same time in the same area are astronomical it doesn't add up. The simplest explanation is usually the right one.
