Also i'm used to doing 50% weekly water changes for my Flowerhorn, how much water should i change on a smaller community, i have always kept large South and Central American Cichlids for the last 10 years, any smaller communitys i have kept where in smaller tanks.
for a 60 gal tank I would try 5 angels, a group of a dozen cories and a big school of maybe 2 dozen tetras. lots of plants and dark substrate. try 25% water changes or less every week or 2. enjoy.
