i am having problems with brown algae growing on some lace coral that i have in an african cichlid tank, i have 2 electric yellows, and two electric blues and one pleco. I know that the pleco will only eat the green algae, an even if he could he cant eat it off of the coral (too rough) what are some things that i can do to either cut down the ;ugly brown growth, besides limiting the light? is there another fish i should get instead of the pleco? I was thinking aobut trading him anyways. (I didnt realize he would get to 20 inches.) I have heard that bristlenose pleco is ok in cichlid tank, but it still wouldnt be able to eat it off of the coral.(correct??)i would like to have a fish do the dirty work, rather than chemically treat the water. Thanks for any advice. all is apprecitated.
