some dont need much light at all. i think the more fancy they are the more light they need.i have about 3 wpg
no flour. lighting and some of my plain reds live in the shade under rocks. they reproducing as well as the ones high in the tank. i know yuma's and ricord's need higher light.
some say suplamental feeding will be needed but mine do not seem to want anything i give to them.who really knows. i just know that they are easy to please. that i like.
