Sexing Snakeskin Gourami's

[Eläköön]

ive got 6 of these guys, biggest are around 4" so far. one of the smaller one is developing red eyes, is this a male trait? other than that theyre all pretty similar. i couldnt find any info on the net about sexing them
but i thought i read somewhere theyres a type of gourami who the males are red eyed and finned while the females yellow

females will usually have a very round belly and the males are thinner. the males will also be less colorful than females full grown.

thanks for the info woofy!
so this one with the redder eye will be a female?
i think they should be sexable within the next few months. thankyou
