SAEs will eat a Mayaca species which I keep. I believe someone re-classified it as Rotala sp. "Nanjenshan". I'd be surprised were they not to molest R. wallachii as well. They tear at my hygro leaves, but don't seem to bother the Eusteralis stellata. Both plants are a real challenge as a previous poster has mentioned. -- Dave Whittaker Gloucester, Ontario Canada ac554 at FreeNet_Carleton.ca
