This is a perfect example of misidentification I believe. Both fish in the video appear to be dovii and not a hybrid at all.Here's a link to the jag X dovii.

Certainly looks to be that....then again tough to be certain, with out seeing the parents with fry. IMO the fish does have more resemblence to a dovii, though jag characteristsics do seem to be present. That's one opinionOn a side note, the fish has the spot at the base of the pectorial fin....like a jag or dovii.
