Attacked by a Giant Fishman

Damn, these giant fishmen are beginning to piss me off! Me and Tara left the vault, and we're trying to avoid the giant fishmen because of her injuries, but we're not having any luck. We were attacked by one of them shortly after we left the vault, and we were just attacked by another one. Fortunately, we took them down pretty fast, and Tara hasn't received any further injuries.
