Hi: At the risk of sounding very dumb, can someone clarify for me what species are CAE's and SAE's. I also assume that CAE = Chinese Algae Eater and SAE is a Siamese Alge Eater. At my LFS I have heard and Otocinclus referred to as both a CAE and an SAE. What is a Flying Fox catgorized as? My Oto's seem to do a great job on brown algae, but the don't seem to touch the green. Any suggestions? Peter
