I have memberships to dozens of different forums (aquarium and other), planet catfish, cichlid forum, aquaria central, aquatic photography, reef central, reefkeepers, NZMAS, oscarfish.com, waterwolves, simply discus, arofanatics, etc etc, but the only other one I read on a regular basis is Monsterfishkeepers.com. I've been a member since nearly day one as I knew one of the guys who set it up off another forum, and the sheer volume of experience on nearly every aspect of the hobby from building to breeding to photography to importing is unsurpassed. This forum is great for local knowledge (and yes there are some very knowledgeable people here), but the DIY and Set Up & Filtration forums on MFK and the regular users who frequent them are gold for anyone interested in large tanks.
