Ocellaris are supposed to not have markings on the cheek, which makes me think mono, but I am definitely not an expert on IDing bass. I am mainly just trying to apply some things I have read.
Not a 100% way to ID a Ocellaris.. Gotta go by the shape of their head... Monos get red eyes at times too. 24/7 red eyes means there is a possibilty of Ocellaris.
