This one is the largest of the 3 i have, he takes on my agressive Midas/Red Devil mix and it takes alot for him to back down, and for prrof of his size, thats my 3" male convict next to him.
I know i said i have 3, but i havent got a pic of the 3rd one who is really small but sticks up for himself against the big one, i will get some soon of him.
The large shark in the first pic bit my hand once, i didnt feel any teeth, but i did feel a huge amount of pressure, it felt like the side of my hand was ready to crush.
