I might have the chance to get a FREE (or next to free) 100 gallon tank. I think I would like to try my hand at cichlids...maybe convicts? What do you guys think I should do? I would have to purchase lighting, filtration, airpump and a heater, but the stones and tank are free, so I can purchase whatever necessary to accomodate a nice group of cichlids. Thanks for help/advice.
