Hey all I recently got a 20 gallon aquarium setup and am looking to start adding fish. How many fish can I fit in my tank? I'm planning on getting cichlids any suggestions on beginner ones?
Make sure you have a good read of that link that EA posted (also found in my signature).
You need to do a fishless cycle before you add any fish, if you add lots of fish at once, they will likely die from ammonia and/or nitrite poisoning
