    Just got home from work and noticed both of my sharks were out. The rainbow (male) who is generally docile was the aggressor, which I thought was odd. I watched them for a few minutes and it turned out they were mating.

    Probably not. They are different species.

    That's what I figured, but they're definitely trying.

    They are close relatives, so I would consider a cross possible, but it's more likely they are just fighting. Not all fish fights look the same. And these species are known to be fairly intolerant of conspecifics (i.e., fish that look like them). Maybe the Rainbow just decided he'd had enough.

    Generally, both species are commercially bred by injection of hormones. I have never heard of any untreated fish spawning in aquaria.
