Life's little ironies. Scotty got his from Denver tank collector who got his from me. So if Scotty's don't eat plants and DTC doesn't have an issue I guess mine must just be starving, or my plants are very tasty. Probably the starving one, I keep my tanks really clean and I am always pulling out empty Spixi shells. Will go 10/$1 just to get my population to a healthier level. Also will trade for tiger or leopard nerites.
