Molly Troubles

Info: I have 2 pairs of mollies 2 yellow, 2 white mollies. Tankmates are 14 neon tetras, 4 mollies, 3 balas, 5 swordtails. 60 gallon tank with 2 Rena filters

This morning I saw some baby mollies and took it out into a seperate tank. I noticed that one of my yellow mollies has a white patch around the forehead. The rest of its body looks fine. The rest of the fish look fine as well. As I caught the fry, I noticed that this molly was harassed and went into hiding. Is that white patch a disease that was attained from stress?

Also, I noticed that one of my white Molly has like a black coloring on the edge of its tail. I never noticed that till today. Is that disease related?

Please let me know if you need more info.

How big is your tank, how long has it been running, what filtration do you have and what's your water change/maintainence regime? Do you have the results of any tests on your water you could post?

60 gallons, has been running for about 4-5 months, 2 rena filters and an air pump, and I water change about once every two weeks. Don't have any results.
