 I was thinking with how aggressive a Betta can be , Do aggressive male fish Produce Testosterone? How about any male fish for that matter?

You're welcome Karen. I'm into biological science and I love Bettas. I've kept and bred them since 2004 but I'm taking a break from them atm. I plan to get back into them later this year :)

Cheers,

Stefan (pronounced Steff-an not Steeven :p ) .
