I have 2 adult tiger oscars, a pair. They were rubbing on eachother over a piece of slate I put in for them. I said "yay!". Then my male started wiggling by the female, but twisted himself upsidedown! After they were done wiggling he quickly righted himself, and they circled around, and he did it again! They did that prob 3, maybe 4 times. I've never read about this in any breeding behavior article, or anything else for that matter. Otherwise, he's acting 100% normal. They have wiggled together like they're supposed to. So, any ideas? Is he sick, injured, or is it just his way of serenading her? Thanks.
