Hi. Im a bit worried about my Molly. I noticed he had a red mark near his mouth 3 days ago which seem to disappear over night! Then yesterday I noticed a couple of white spots on his fins and today he has more spots on his fins and now tail and what appears to be a yellow spot behind his fin. The water was changed yesterday and all the readings appeared fine. He's his usual manic self, flying around the tank and still eating. The 1st pic is the red spot the 2nd is today with the spots on his tail and the yellow dot near his fin. Its a 50ltr tank and he shares with 2 tetra and 2 Guppies.
