It would be nice if you could get a couple more as they really do better in groups of three or more. It makes them much more active as they are timid little fish if your tank is big enough to support the fish. At least 10 to 15 gallons is needed for them and they will be very happy. To breed them you will need to do a water change with slightly cooler water (a couple degrees or so) and provide lots of cover. Make sure that their tank is not inhabited with other fish that will eat the eggs. They are fun to breed.
