These are another of the species that are hard to pin down exactly where they came from, because they are commonly captive bred and the original "parents" aren't commonly imported.
It is POSSIBLE that they are
, but without further details of for example where they came from, it's pretty difficult to say because there are other species that look pretty similar, but can be differentiated by different capture location [and assuming the scientists doing the descriptin described it properly, it can PROBABLY be differentiated by other means - but that may be difficult for the average aquarist, as it often means killing the fish to identify internal characteristics, or at least counting small things under a microscope or very enlarged photo].
