Very special thanks for the first two photos for this unique clown to Soren Hansen from Sea & Reef Aquaculture, USA.

Not only is the longfin clownfish from Sea & Reef Aquaculture a real fish, but we’ve also got the video to prove it. The real April Fool’s joke of yesterday’s posting of only the second known longfin clownfish to be documented is that this endowed black Darwin Ocellaris is not only real but it is radically long-finned. The high contrast and black coloration of the teaser pictures of the black Darwin with extra fin-sauce helped to hide the fact the pictures were real, although they could easily be reproduced in photoshopped.

Adding to the mystique of the black Darwin longfin clownfish is the lopsided elongation of its fins with one pectoral fin being completely normal, and the other one draping to the side of him wildly like a cape. The tail fin and soft portion of the dorsal fin are also incredibly enlarged, leading us to wonder how it is that the long fin trait is so extreme in this clownfish, like a gene that has stimulated those fins to grow instead of just slightly longer finnage as is usually the case with freshwater fish.

So what’s next? As we reported yesterday this studly longfin clownfish is already earmarked for Sea & Reef’s breeding program, and it will be only a matter of time until a whole crop of longfin clownfish are available in a black ocellaris clownfish, and we’re really curious to see how it comes out. Big thanks to Sea & Reef for helping us to play this reverse April Fool’s trick on you guys and we wish them the best in producing more longfin clownfish to add to the diversity of captive bred and designer clownfish.

Longfin clownfish are still the white buffalo of the captive breeding world and now it looks like we’ll be seeing longfin clownfish from the black Darwin ocellaris. The Longfin Darwin Ocellaris was found by one of Sea & Reef Aquaculture’s attentive staff Brandon Weik. He spotted it in one of our grow-out tanks among thousands of regular black and white Darwin ocellaris.

Not surprisingly the unusual looking Longfin Darwin Ocellaris was attacked by its fellow tank mates and its fins were already ripped some. After rescuing the poor Darwin Longfin and isolating it in its own tank the fish grew quickly and we were all surprised to see the size of its fins as they grew back. One interesting note is that the right pectoral fin and first dorsal fin of the fish are completely normal while the rest of its fins are greatly enlarged.

Take a look at that left pectoral fin. Some people would call it a lucky fin, but with elongation like this it really is more like a lucky cape! The Longfin Darwin Ocellaris is now destined to become a broodstock fish. Sea & Reef intends to find out if the genetics behind this longfin mutation will be expressed in its offspring and they are currently searching for a suitable mate with a liking for the unusual.
