Ha ha ha.....I used to have a 13 inch Texas/Flowerhorn cross and he was MEAN...He would let me pet his head when I would approach him with my hand in just the right way....Friends and people dropping by would see me pet him and think it was really neat and, in turn, they would like to try........Soooo of course I would say yeah go ahead he only bites stupid people.....and sure enough as soon as their hand would go in the tank WAM! my fish would attack them and usually draw a good amount of blood....They would freak out and ask, "Why did he do that?" and I would respond "Because you were stupid enough to reach your hand into a wild fish tank"
