It's really sad.. It's not a freaking betta fish! If you want that type of fish then be prepared to drop the money to provide it with a suitable living environment. I would love to get tangs but would never even think of putting them in my 55..much less a 6 gallon.
If you ever watch animal hoarders its always dogs, cats, birds, horses.. Things of that nature, but you will never see fish.. Cruelty to ANY animal, whether on land or in the sea or hell, even in you neighbors pond, is disgusting.. People like this make me sick.
I'm gonna go do a water change
