With regard to hair algae - My african cichlids (mbuna) love hair algae - I harvest it out of my tanks and put it in my malawi tank and the fish eat it up by the next morning.. Many of my young fish eat the protozoans they find in it. ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
