Freshwater Aquarium/Cichlid tank


Okay I have a 30 gallon tank with six cichlids in it. I have one female yellow lab. One male cobalt blue. I have two kenyi one male one female. I have one male yellow fin acei and one female black white fin acei. I'm having aggression problems with my male kenyi. Some people have told me to add more fish To my tank but I thought the rule was 1 inch per gallon.  I also heard that I should add an aratus Cichlid to my tank To give my Kenyi a run for his money. So should I add more fish or should I add the one aratus?

Hi Stephanie

Your tank is already at capacity, adding more fish will only add to the aggression problem. With Cichlids, there will always be aggression. You can try rearranging the tank decorations periodically to disrupt territories, that sometimes helps. If the Kenyi is making contact and injuring the others, you may need to remove him from the tank. If there is just chasing etc going on, I would leave it alone.

Hope this helps you, good luck!

I own and maintain several freshwater aquariums from 2 to 180 gallon. I can answer most questions about freshwater aquariums, including setup, cycling, maintenance, compatible tank mates, feeding. Moving? I've moved fish both across town and across the country and can help you get your little aquatic friends to their new home safely. I know and have experience with most freshwater community fish, South American Cichlids and African Cichlids. I don't answer questions about Goldfish or keeping Goldfish with Tropical Fish. I also don't answer questions about keeping crustaceans (shrimp, snails, crabs etc) with Tropical Fish, nor questions about saltwater fish or aquariums. I'm not available to answer questions on weekends, this is when I do maintenance on my own tanks.


Many years of personal experience with community tank fish, semi-aggressive fish (Barbs, Tetras, etc), Angels, South American Cichlids and African Cichlids.
