This time, I think I'll let the pictures speak for themselves. I think the fishes' expressions say enough.
First off is the Oyster Toadfish. While he's strong enough to crush shells in his mouth, he's actually quite a good parent, watching over the nest until a few weeks after hatching.
Next up is the Reef Stonefish. I definitely think he wants left alone, and I think that's the best idea. His spines contain one of the most toxic fish venoms anywhere.
Last up is the Stargazer. A nice, lovely fish with the ability to produce 50 volt electric shocks. Oh, did I mention he's venomous too?
I definitely think that when someone looking like this wants left alone, the best choice is probably to let them.
