I agree with the other posters. A good mbuna tank is always a nice
start, and in fact, always nice period. I've been in the hobby since
1988, and still have an all mbuna tank today, they are beauty's. 55
gallon is perfect. As the others said, keep good filteration, a weekly,
no worse then bi-weeekly water change ( 50% to 60%), a good 7.0 PH or
so, give them plenty of rocks ( natural habitat look), I like to stack
them to the top, making caves here and there. And toss in some good
plants here and there, might as well grab just a few plastic ones, as no
doubt, mbuna's dig, dig, dig. Enjoy.
