Unfortunately there are some sellers in the hobby claim that HRPs are like most other Centrals and color up with age.
Real ones are blue from the start. These juvies are under .75". Bad picture, but the colors come through for reference.
it does have some red in its tail and anal fin, I think its new and it needs some food and time to settle down before it shows colours.
it most likely is a hybrid of the two but you may be suprised to see it colour up identical to the other pictures.
I´ve seen some amazing before and after pics on here and sometimes a new fish looks like something completely different.
