Yep, I've been keeping African Cichlids for a little over 4 years. I plan on upgrading to a 90G and moving the haps/peacocks to the larger tank. The tank is actually a 60gallon (slightly taller than 55G) but fits perfectly on a 55G stand. The 55G will remain for the Mbuna's. There's also a 10gallon half-moon tank that I use for the yellow lab fry. The livingstonii is a female that I've had for a little over a year and a half, and she hasn't grown at all, surprisingly, beyond current size. She also holds infertile eggs on a regular basis, which she then eats. All sorts of interesting things happening in the tank. Thanks for your comments!
