Hey everyone I'm new here.I have a 5 gallon tank with 2 platys 2 variatus and one gourami. One platy is a female the other a male.recently the male has been following her EVERYWHERE..then just today she moved into a little house sunk to the bottom and didn't move.when she finally came out her fins were clamped in and she's a little jumpy.also at an angle it looks like she has white spots.what do you thinks going on?ice maybe?or does the male have something to do with it?thanks for any help
