I have six of the 7 bar kigoma frontosa around 2.5 - 3 inches and am still trying to learn more about them. I have been told the hikari cichlid excel and new life spectrum is good for them. They are in a 170 gal tank. I am trying to find some info on all the different types of frontosa as well as should i be offering some live foods? I would only do live if it's better for their health.
