I believe these are the same critters that Oliver Knott

No, they're not the same. Oliver Knott was recommending Neritina natalensis, which are smaller than Olive nerites (Neritina usnea), . Here is a picture and description of the Olive nerite, which George Booth recommended:


and here are several pictures and description of Neritina natalensis, which Oliver Knott talked about at the AGA convention:


Although Oliver Knott wrote me that they are available in Germany, they're not supposed to be imported into the U.S. I tried, unsuccessfully, to get an import permit. The whole matter became moot for me when all my algae, spot and otherwise, disappeared. I believe this was and is due to the rather heavy fertilizing regime recommended by Tom Barr (10 ppm nitrate and 1.5 ppm phosphate four times a week, with Seachem Flourish and Seachem Iron on the other three days).
