Hi, i just set up a brand new 55 gal and am making it an african cichlid tank. My friend has 20 or so africans that he wants to gte rid of as he doesnt have the time to care for them. I know these fish have been through some rought water conditions, for example only cleaning his tank once every month or month and a half. The fish still show pretty good colouration but nothign like the local big als. I was wondering if i take them off his hands and properly take of them will they colour up as nice as onces bought as juvies? Also what should africans be fed to promote strong colours? Thanks for the help!!
