There are many species of cichlid that could be kept in a 20 gallon tank. The important thing is to follow the basic rules of sucessfull fish keeping. Those rules are. :- 1 inch of fish needs at least 1 gallon of water. :- Every tank needs a permanently running cycled filter. Every tank needs at least 50% of its water replaced every week. If you do all the above, feed the fish morning and evening and keep it/them at the correct temperature your fish stand a chance of survival. If you fail in any of them I can guarantee that your fish will be constantly getting sick and will live shorter lives than they should.
Any fish that doesn't grow too big would do well in a 20 Gallon(80 Liter) aquarium. You could put about 5 goldfish in it or a lot of smaller fish like tetras. Just be sure whatever you put in there together doesn't eat the other fish. You can find a fish compatibility chart in the sources and related links(below).
