A rare double-finned common firefish has just made its way to the aquarium hobby and it’s quite the attention grabber. If there’s one thing that firefish are well known for, it’s that prominent first dorsal fin. So you can imagine our delight when House of Fins turned us on to a very special individual with not one but two first dorsal fins.
While some groups of fish like surgeonfish and angelfish show a high degree of natural variability, common firefish are so standard-issue from one specimen to the next that they may as well all be stamped from the same mold. This is why we really take note to any variability of Nemateleotris magnifica when these specimens do show up.
To date there have only been three previous aberrations of this highly uniform species of dartfish: the Monochrome firefish, the hybrid firefish, and the extremely unique one-off pink-spot firefish. The new double-finned firefish is a welcome addition to a very exclusive of this group of fish we adore so much.
Thankfully, the double-finned firefish originated from Africa which is known for growing N. magnifica quite a bit larger than they do elsewhere. Better yet, the very rare double finned firefish is now part of a group of its kind living in peace and on display in a show tank at House of Fins where many visitors will be able to marvel at its peculiarity.
