A couple of days ago, I changed my American cichlid aquarium into an Australian Rainbowfish aquarium. However, me being so used to working with cichlids, did a 50% water change on my Rainbowfish aquarium, killing all of my Rainbows. I drained the entire aquarium and refilled it. Now, about 6-7 days later, I have transformed the barren aquarium into an Lake Malawi African cichlid aquarium. I originally began my cichlid experience with African cichlids, before I switched to American cichlids, but I only had kept mbuna. In my 38g aquarium, I have fully stocked this aquarium with 8 juvenile African cichlids and 1 Red Tailed shark. The African cichlid stock consists of mbuna, a peacock, and a hap. I have a electric yellow, a red zebra, an ob zebra, a red peacock, an acei, a electric blue johanni, a taiwan reef, and one yellow and black cichlid that looks like the johanni, however I cannot recall the name at the moment. All of the fish in the aquarium are an inch or smaller. I've been experimenting with my filter media, in order to find the perfect media for my tank, which is low maintenance, and rare maintenance. So far, I have been at peace with using lava rock media in my Penguin and Aqueon hang on the back filters. In combination with lava rock, there is Golden Pathos in my filters, which in combination, does an outstanding job with filtration. My water is crystal clear, ammonia is at 0, nitrites are at 0, and nitrates are at 0. My pH is at 7.2, which is directly from the tap, I do not have any buffers in my aquarium, other than a few natural rocks. I plan on planting the golden pathos inside of the aquarium, (it is possible, if done it plenty of times before). You could consider me a novice at keeping African cichlids, but intermediate at keeping cichlids other than Africans. I am wondering if my stock of these 8 ACs is overkill or underkill for my little 38g. I know it is a risk combining mbuna with peacocks and haps, but thus far, in the little time I have had them, I have had no problems with aggressive. That may change in the future. So any tips on African cichlid keeping would help. I have already watched many different African cichlid keeping youtube channels, such as Mbuna Marcus, African Cichlid Hub, and KGTropicals. Pictures coming soon.
