It is certainly profitably to be called down by the fish but make sure that when you hold AA and are betting and being called on a 2 flush 2 straight flop that you are prepared to fold when that card comes that completes the draws.
If someone will pay anything to draw then you have to put down hands when those draws complete.
If you dont you will lose money through bad beats. If you do then you will make money from overcharging people for their draws.
