sick black mollies

[beernboots]

I have nothin but problems with my black mollies but they are my favorite fish. They come to the side of the tank when I get home, peck on my fingers, and allow me to pet them. Really sweet fish but they keep getting different kind of sickness. How do I keep them healthy.

I seem to keep having the same problem with my black mollies. I use salt water baths for the most part and it helps. My problem I think is I get black mollies from Walmart. Check your waters nitrate and ammonia levels.
