VIDEO – Wild-type Variatus Platies, In Situ, But Where?

Footage uploaded to YouTube in 2010 highlights a population of beautiful, polymorphic Variatus Platies. But is there more to the story?

Every once in a while AMAZONAS staff stumbles across a video that stops us in our tracks. This week, for me, it’s 5 minutes of in-situ, underwater footage showing the male polymorphism of Xiphophorus variatus, with dominant males sporting either yellow or red tails. These wild-type Variatus Platies or “Platyfish” are remarkable & highly attractive.

The footage shows males Xiphopohrus variatus with both yellow and red-orange caudal fins.

A mysterious locale…

However, It’s unclear whether this footage, at a location called “SKHC”, documents a native population located in the Americas, or a feral/introduced population in Hong Kong, as some of the comments suggest.

This stunning male aggressively courts a female, attempting to elicit a mating response.

The video was uploaded back in 2010 by, which sadly appears to no longer exist. Thanks to the amazing project of the Wayback Machine (a.k.a., nothing on the Internet is usually lost. So, you can still head over and sift the archives of over there! (and maybe kick in some financial support for if you appreciate what they do!) Of note, I did manage to uncover this beautiful image of these fish that had been preserved in the Archive.

Sadly I couldn’t find any more info on the “location” of “SKHC” even when I managed to dig into the source. Meanwhile, the Internet thinks SKHC is somewhere in Colombia…

There may be clues…

If you pay close attention, you’ll catch glimpses of other fish species in this video. The male Swordtail is rather obvious, but the others are blurry at best.

A male Swordtail, presumably X. helleri, zips in and out of the frame a few times during the video.
This species of silver fish with a black horizontal stripe (upper right) appears several times in the video. Is it a characin or cyprinid?
This angular-bodied fish (lower left) appears reminiscent of a barb, which might lend credence to the idea that these fish are a feral population somewhere in Asia.
Is this a goby resting on the rock at lower left?

Perhaps you’re the AMAZONAS reader who can help us unravel this mysterious location with definitive certainty? Think you can help? Check out these screen captures, watch the video, and share your thoughts!

    I found this youtube video, what looks like someone has the SKHC in their home aquarium.
    Hope this is helpful. I would love to have these swimming around in my aquarium.

    This platyfish pictured at the bottom looks very similar to x. Variatus ‘La Minzita’.

    The black-striped fish doesn’t match any Mexican species, while the barb and goby strongly support an Asian locale for the video footage. Wherever they are located, the platies are obviously doing very well for themselves.

    I think this is very likely to be in Hong Kong, or at least in southern china. The black striped fish is indeed a cyprinid, which is likely to be a juvenile parazacco spilurus.The barb seems likely to be the wild form of the gold barb and I don’t know what the goby maybe(it is unclear)
