I've bred Australian black and regular orange occ's... bred chocolate and black... I am not a scientist and I am not going to waste my time trying to study it but it does look like a mix between a black and regular orange occ. like what mine looked like when they grew up. Most of the blacks look like maroons with the bigger/ fluffy fins and they bob more then swim. I've noticed this with my set-up though and everyone sees different stuff. I used the tile in my tanks as well and transported it a couple days after they were laid to their "growing station" where they would hatch that day or the next. So about 5 days. Otherwise they are food for your tank if you have them in a DT. But my point was... that looks like a Black and Orange mix.... either way, they're all pretty. AND I WISH I COULD FIND A RED ONE LIKE GEEK HAS! PRETTY!
