Probably got into a fight. My Congo Tetra's squabble a lot, as do my Gymnogeophagus Terrapurpurra. It's not uncommon to find them with a little scratch.

Oh! I hadn’t thought of that. I will post a photo tomorrow. That tank is really getting crowded. We gave twenty away last week from our third tank.

Excess mucous caused by something in the water irritating the fish. It could be poor water quality (ammonia, nitrite, nitrate), low pH (mollies need the pH to be above 7.0, or the area was damaged and the fish produced more mucous to help protect the area, or it's an external protozoan infection.

Check the water quality.
Do a 75% water change and gavel clean the substrate.
Add a bit of salt (1 to 2 heaped tablespoons of rock salt for every 20 litres (5 gallons) of tank water. Keep salt in there for 2 weeks.

If it gets worse after the water change and salt, post more pictures and post the water test results.

You should also check the GH (general hardness) and KH (carbonate hardness) of your water supply. This information can usually be obtained from your water supply company's website or by telephoning them. If they can't help you, take a glass full of tap water to the local pet shop and get them to test it for you. Write the results down (in numbers) when they do the tests. And ask them what the results are in (eg: ppm, dGH, or something else).

Mollies need a GH above 250ppm.

True, looks like a water quality issue to me

The lighting is terrible at this time of the day, but Native Son definitely has a silverish patch.

Thank you so much. We are going to work on our Mollies tank tomorrow morning. That spot is so hideous…I want to get the situation handled as soon as possible.

It's just excess mucous. All fish have a thin clear layer of mucous over their body to help protect them from microscopic organisms, chemicals and other irritants in the water, and to help them move through water easier. If the fish is stressed or injured, they produce more mucous, which can appear as a cream, white or grey film/ patches over the body and fins.

It's just an indication something isn't right in the tank or the fish has been injured.
