I absolutely agree with the correlation that you have found. I am a recent college grad and have kept cichlids and piranha for about 7 yrs. I have definately been known to drink a bit and currently have large aggrsive cichlids. Also one of my buddies and perhaps one of the biggest drinkers and partyers I know, currently has huge jags and oscars, he has also had piranha. Another thing I think you have to consider with large agg cichlids is pot smokers. Me and my buddy LOVE to smoke a fat bowl of chronic and one of the better things to do for the next hour or so is wathc the tank. LOL. I'll be watching TV and then just end up watching the fish for the hour. Give it a try some time.
