Find the shop with a knowledgeable person. You can get various peacock cichlids. Pick up a couple of Regal peacocks and a couple of yellow peacocks also called Sunshine peacocks. Once they get to about two and a half for 3in they color up beautifully. Females have little color and will not be nearly as pretty as the males. Another beautiful fish is the Jacobfrabergi. If you get about three of each of these along with a catfish or two you will have an ice tank and as long as you don't mix other Genuses with them you should not have any problems with aggression. They are very easy to keep. You need hard alkaline water. Set up your tank without any fish and let it run for about 3 or 4 weeks before you start adding them. Use crushed coral for your substrate because that will keep the alkalinity High. once you get your tank going and you have it stopped he will have a beautiful set up.
