What size tank is yours in? He looks way bigger than mine even though he's only a couple inches longer from your estimation. Mine is in a 220g. Or are you saying 11" SL (to caual fin). I'm using TL (head to end of tail).
You also said you've had yours 5 yrs. How big was he when you got him? I actually had a pair, but the flathead ate one recently (pissed me off - didn't think he was big enough to get one down - he's now in my pond), and that one was an inch smaller and not as thick, despite having had them the same amount of time. I dunno if it's a male/female diff. or what, but my bigger one has kind of a hump behind the head like yours, and the other one didn't.
I want to get another one since this one liked having a companion, but it's gonna have to be one around the same size as the last one at least, as I don't feel like growing one out for another 5 yrs.
