i have read all over the internet that it is impossible to tell female or male oscars apart except that sometimes males have three dots somewhere or the female will lay eggs lay eggs. My oscar is still only 2.5 inches and i was wondering how to tell if mine is a male or female like behaviour types or something.

oscars are monomorphic ...which means males and females are identical and show no differences in any aspect of their apearence whatsoever .... and cannot be sexed from just looking at them ....they need to be "VENTED" to determin the gender ..

whats "VENTED"

scrutinising their genitalia

You can tell the difference between a male and female Oscar by looking at them, but you've got to know what you're looking for and it will involve removing the Oscar from the tank.

venting is basicaly all i can describe to you as an "internal examination" only to be performed by very experienced fishkeepers/handlers ....or fish vets

they got to check the ventral side ( i guess thats where the word from) aka checkin his/her ass to decide wether its a female or male. males are O o females o o ( if i recon correctly )
and again they need to be quite old for that as far as i remember

and since they are very small vents in the abdomen,
you can be sure that the evaluation is correct. there
are many factors affecting the venting: first is the
stress it will make to your fishes by removing in the
water; then the mild squeeze in the abdomen; and the
time limitation during examination.

do you want to put your fish just for that reason?

thanks i don't think i'll do that

but you can try to put a mirror at the bottom of your
tank. and whenever your fishes pass-bye or swim over it,
you could have a glimpse of their genitals and see those
holes near the fin. you have a chance to see two identical
round holes or two different size holes in the reflection.

dont try that on humans or you will find yourself slapped or even worse i jail
