Same species: One fish with blue fins and the other red?

[hexabonal]

Hello everyone,

I uploaded some pictures of what the store claimed was the adult version (apparently) of these juveniles. Mike said that they were A. Regani complex. Interestingly, the colouration of the fins is very different indeed. One fish is noticeably larger than the others and has red fins. There is another smaller one with red fins, but also another smaller one with bright blue fins.

Could this be a difference in gender?

They are at about 2-3cm so far. They generally hang out in close proximity and have not shown any aggression yet.

Sorry, but color is not a major factor in apisto identification. At the size they are presently, they probably are still juveniles.

Looks like a probable female and male, based on fin color; just hope they're the same species.
