Apistogramma caetei?

[Nestorix]

Hello everyone! I've ordered two apistogramma caetei (1 Male / 1 Female) some weeks ago, is anyone able to confirm the species and sex?

While I can imagine that someone with more experience might be able to confirm the species, but I'm very sure it's still to early for a save sexing.

I'm not able to savely sex them either. But it's a steindachneri-group species, likely A. steindachneri itself.
