betta unimaculata

[latapy10]

Hi, I have a hypothetical question. Could anyone tell me if a male betta unimaculata meets a male betta splendens, would they fight to the death or ignore each other?In aquarium conditions.thanks.

I can’t speak for unimaculata temperament, but splendens has been selectively bred to get the most aggressive males possible. They will go after anything that slightly resembles a threat. I see no reason why the splendens wouldn’t try to kill the other betta.
Definitely don’t try this mix.

Thank you for the professional answer.
