Sexing Red Tail Triggers?

[LBC]

I got a Blue Jaw yesterday. LFS said its a male.

I put him with my unsexed Red Tail. Surprisingly, they got along from the get-go and even spend time swimming around together.

I will not even be attempting breeding them, its just cool to see them together and then it dawned on me is my Red Tail a boy or a girl? He's twice the size of my blue jaw.

Any way to diferrentiate Red Tails' sex?

Both of those species are sexually dimorphic. Sexing them should take all of two seconds or a google search for pics.


Size is also an issue since smaller individuals will most likely not have much color until they mature or turn male.

Guy,

then i should be able to sex my Red tail, since s/he is huge.

however, i have been able to find zero info on this species being dimorphic (compared to blue jaw/throats)

HELP!!!

Males will leave you with no doubt. If it's dull or not significantly colorful in the body it's probably a female.

I should have specified my Red Tail trigger is from the ATLANTIC:
Sargassum Trigger (Xanthichthys ringens)


I forgot some of the other species with red tails like the Crosshatch (a Pacific trigger) you linked, are sometimes called Red Tailed.

I guess there is no way to sex X ringens?!
