here are some tigers that didn't make it, is this close enough to a black goliath? but seriously, look at the jaw of this beast, came in dead, probably was a black goliath, look at the blue steel coloration and the huge head!!!!
not all fish turn dark when they die, many turn white, and tigers certainly don't turn black. for all those people who hate, doubt, sour grapes., hope this answers your question. i've had tigers fresh dead, to dead for years, in and out of water, non of which turned black. so stop hating. Please refer to these pictures, I took them, I have more pictures of dead tigers, different stages of death, I'll post them up when I find them....
