Salt and Corys! No i say. But i know of it happering and stoping Ich. Loaches do come from certain regions where they interact with Brackish waters and i know my friend in Thailand say's this is how they "clean themselfs" BUT! this is in the wild and home grown or import loaches dont know this. Loaches can be treated with salt but it must be a small treatment.
