Questions about Red Robins - T. chuna x T. labiosa hybrids?

[Ivanlebron]

The fish that are sold as Red Robin Gouramis are a line bred red variety of Trichogaster labiosa. Labiosa and chuna don’t hybridize. If you could provide a picture of the mystery gourami I’ll be able to give you a definite ID.

Could u help me identify the sex of these fish as well as if they are t labiosa ? Ty in advance

Both are Trichogaster labiosa. The one on the left is definitely a female, but I’m not sure about the other one. How large are they?
