I just got these fish yesterday: Sunshine Peacock (Aulonocara baenschi), Red Zebra Cichlid (Pseudotropheus estherae), Jewel Cichlid (Hemichromis bimaculatus), and one other that I'm not sure about. My tank is a 55 gallon with a penguin 330 on it right now and I planned to add more filtration. I found that the Jewel Cichlid is from a different area. Also can I add more fish? The guy at the lfs told me I could have 8 african cichlids in my 55 at max. I was thinking more what do u guy think? Thanks for any advice.
