Freshwater Aquarium/Fish Compatibility


Hi, I was wondering if you could help me out right now I have a 55 gallon aquarium setup in my house and i currently have 2 giant danios 1 striped catfish 1 iridescent shark, and 1 African brown knife. So my question is would it be safe to add some cichlids to the mix. If so what would be the best for my aquarium size and the fish that are already there.

Hi Nick

There are only a few Cichlids I can think of that will go in your tank that will not eat the Danios and the Catfish. These are Angelfish, Kribensis and Keyhole Cichlid which are easy to keep. Ram Cichlids will also work but require very clean water and are a little more difficult keep.

Hope this helps, 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.
