I usually respect agressive fish because they are so innocently selfish and I would rather forgive them. I was lucky to get rid of one of my sharks only because my friend did not have any. If she did and was unaware of the shark's vicious ways how I could give it to her? To ruin her tank?
I think the owner can dispose of their fish as they like if it painless and quick (I oppose torture!!!)
So, good riddance honey!
