minus the hot, sweaty, and replace sex with the act of fertalizing eggs not through sexual intercourse.
My brother picked up 5 fish (and one shark thats pretty baller) for his fish tank the other day of what he thought were all males. Anyways he's feeding them today and there are 2 TINY ass fish swimming around. Hahaha i couldn't believe it. I thought his shark was going to mistake them for food and just eat them. hahha . And there was no way they were there when he first bought the origional ones.\
Is it known to have reproduction with small fishes in a fish tank? I didn't think so.
