as we all know that sexing oscars are difficult, so what i did is i bough about 6 3 inch oscars and placed them on a 75 gallon tank. the problem is how do i find out if they're already paired. thanks!
you will know by the tendency to pair of and be alone,lip tugging,digging and cleaning of rocks together...only sure was is when they lay the eggs....tubes males is long and thin and females is fat n short<not always case but 99% sure way...obviously where the eggs come from is female...hehe.....but2 females can also pair up and lay eggs togeter
