I was wondering what would be recommended for cichlids to keep in a 40 gallon tank, african cichlids, I would like to have many not just one or two so no large species, easy care, and easy breeding (cause I think thats neat not cause I want to sell them). I have kept oscars and green terrors (with success)but no other cichlids and have been keeping fresh water fish for 5 years now so I can handle some challenge but I don't want to spend a fortune on fish either. Thanks in advance for any advice.
