Is it common to have differant shades to an OB Zebra. Is it a difference in gender or is it just common to have differant hues. I have two OB Zebras and one is VERY orange, almost neon with very dark black spots and my other one is very pale (almost light peach) with paler black blotches and a blue tinge on it's fins. Both very pretty fish but i was wondering if the colour made a difference in type or sex
