I currently have both and love them equally. They each have their pro's and con's. Watching a community setup can be hypnotizing and there's no better stress reliever than sitting in front of my 125, to get lost in the aquarium. On the other hand, there's something appealing about raising a fish in pristine conditions and truly experiencing the full potential of the specimen. As long as I can always keep a minimum of 2 aquariums, I'll always have both.
