I’ve just recently purchased this red devil and I’m wondering is it a F1 I’m wondering because of how it’s mouth is shaped. And also I need help on sexing my guess it’s a female.
Need a vent pic to sex. As far as mouth shape, I have seen red devils at Petsmart with lips as big or bigger than that. So unless the vendor has some provenance back to the wild, it's whatever you bought it as.
