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.

∙ 13y agoAny 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).

Why is your dalmatian fish chasing other fish?
If you have prettier fish than it in the aquarium, he could be jelous. I know from experience. Or before he was in your aquarium, he sould have been in an environment with more aggressive fish than him, so that made him more aggressive. If you wanted, you could by a net breeder and put him in it if he will fit. That's how I calmed down mine. Just every time you see him chasing the other fish, just put him in it for about an hour (underwater of course!). He should start to calm down. Just MAKE SURE you DON'T leave him in for to long, or he could get really sick.
