Yes I did mike, thanks alot. You know what I think caused it, it wasn't the nls. It was because of stress, water quality, and bad dieting. I hadn't done water changes in forever, I never gave them any vegetable matter, and I just found a dead female ruby green. It smelled awful and it made the water have an awful odor. I did 2 water changes today and added in some Aquarium salt. In a bit I'm heading down to my lfs to get some aquarium clout, more salt, some spirulina flakes, and some water conditioners. Fingers cross that they make it.
