Ironically, the Harlequin Filefish is a guady Indo-Pacific reef fish that our hobby and industry had in fact written off as a “cut flower”, doomed to die in captivity. For decades many in fact did get collected and died in short order. The natural diet of this fish is exclusively certain corals, and in fact, research has shown that as coral reefs die off, this species is the first to vanish from the reefs (because it’s food source has died). This is a fish that may well go from common to facing extinction in the wild as climate change, ocean acidification and pollution wipe out its homes.
However, because of my singular efforts, and through the sharing of my discoveries in CORAL Magazine (article attached), the Harlequin Filefish now has a new future. It was not a governmental, academic, or educational institution, it was an experienced private individual, a Marine Aquarium Hobbyist, who sought out the challenge, tackled it, and gave it back to the world. I am not the first, nor will I be the last hobbyist, to make such a game changing discovery. If there had been a ban, an agreement, a white list of some sort, that said this “doomed to die” fish should never be harvested from the wild and sold, I would have never had the opportunity to make this game changing discovery, and I doubt any scientific or academic institution would’ve ever bothered to do what I did. Given the forecasts for reef loss, I think it is fair to say that the Harlequin Filefish’s fate has gone from “doomed in the wild” to “it may survive in the aquarium industry even if nowhere else”. Credit where it is due, the aquarium hobbyist, who gets his fish from the industry, made a game-changing contribution for the fate of this beautiful fish.

If we look to the freshwater aquarium hobby, we see it already taking on this role. The next time you walk into most any FW fish store, you may see a fish called a “Red Tailed Shark”. That species is extinct in the wild. It wasn’t the aquarium trade, it was damming of native waters that wiped it out. Were it not for the fact that it is a popular aquarium fish, bred in immense numbers in fish farms in Asia, the Red-Tailed Shark would be gone. It exists, because the aquarium hobby exists. The only reason anyone is researching the breeding of fish like the Yellow Tang, is because of the aquarium hobby. I am sure every Hawaiian knows the Yellow Tang, the Huma Huma Triggerfish – these aren’t food fish, but they have monetary value in the aquarium trade. Humankind tends to only preserve that which it values. Banning the aquarium trade ensures you ban a group of people who actually care about the long term wild survivability of the yellow tang in the first place.
