Sexing mcmasterai

[shiver905]

Hi everyone,

I’m looking to sex the following 2 mcmasterai.
First - bare tank
Second one being wild (planted tank)

my wild likely erroneous non-binding guess is the first is a female and 2nd is a male.

The one in the decorated tnak is for sure a male. The other one... although it's yellow-ish, the anal fin and the dorsal are kinda lengthy. So my guess is they are both male.
