I think the big mistake is to assume all tells are the same for everyone. Each tell can be applied differently to each person. Personally, I wouldn't suggest playing a 400 pot based on a tell of a player who's tendancies you don't know. It's really key to be paying attention to them the whole time, and hope they show down a few hands.

Also consider that better players will give off false tells, which is what he was doing, so it really is important to know your player. In this case I might have let this pot go, and hope you get to see his hand. I don't know - the truth is, next time you face off, you'll have a better idea of what he is doing; recall is key.
