lol Well from all I know they get ten inches, they will eat flakes, but I recommend shrimp pellets, my little five incher can't get enough of them. Mine does fine even on the higher end of tropical temps, guess it all comes down to how accurate the heater setting is, as well as the thermometer? Either way, keep 'im in a big tank, like others said before me, 30g bare min. I'd recommend 55g+ so he has lots of room.... double the size for a tankmate is what I'd do, everyone needs their space :3 Just depends on their personalities though I suppose. Good luck, I've always kept mine at 78F even and nothings gone wrong.
