How do I see if my oscar is male or female
? I just got an albino tiger he/she is beautiful I am just curious.
PS He is 4 inches and I got a 7 " senegal bichir. Will the oscar grow fast enough to eat my bichir? :)

Only way to sex Os is to get them to breed and then see wich one who lays egg.
damn ! what about the bichir
 
Can't they be vented?
 
as said only true way is through breeding unless you know what your doing with venting......
I have a 11+inch oscar and two 6inch with a 8inch senegal birchir and they all get along fine,,,

Yes, the male's tube is slanted and the female's is strait down. I'm pretty sure that is the best way to tell.
 
Venting


Oscars are one of them fishes you can't tell the sex by just looking at the fishes, even though some people have claim they can. But than again it's not a valid claim when it's not consistent.
 
as for the bichir...even though they are shaped like worms you'd think they'd be a prime target for large cichlids, but I've moved even smaller bichirs (4-6") into and out of tanks with large cichlids who never even gave them a second glance. I've never had a large cichlid attack a bichir....now that's not to say it's not possible...anything is possible. I'm just saying that IME bichirs do very well with even larger cichlids.
