Okay,
So I've found another contaminant. Another toughie for you guys to mull over!
He is your overall basic silvery fish. He has the body of an elongated barb (More like a Labeo, but more streamlined) (Body has a goldish sheen) with a bold black stripe from eye to tail. Base of tail has an enlargement of the stripe.
Looks like a black shark crossed with a flying fox (But remind yourself of the coloration given above)
He is 3 inches, very robust, a very powerful swimmer and very active and very outgoing.
His whiskers are very apparent, not "hidden"
Anybody? Oh by the way, the dorsal fin is very prominent and high.
