I was wondering if anyone has had success keeping live plants with african cichlids? If so, what kind of substrate is recommended? I have seen a lot of tanks on the internet with white (or very light tan) sand and live plants with africans. I would like to do this with my tank but I'm not sure what to use. I have some dry aragonite from Caribsea from a previous tank that I was thinking of mixing with the Caribsea crystal river instant aquarium (about half and half). Would this work? Any input would be very appreciated. Thanks!
