Pink Bubble with White Fuzz

[GoldfishGoddess]

I know I was not prepared for this, I should of got more info on mollies (sailfin mollies) before I got them and mixed two of them with my one goldfish. I thought they would be alright tofather. They were, they did no harm to eachother, but all of a sudden, Moka, one of my sailfin mollies, got some sort of diease near his mouth. He is a sailfin molly, a tropical fish.
The diease looks sort of like a fungus growth (white fuzz), I think, but it has like a pink pimple it is growing from. I don't know.
Please help if you can. I moved him to a five gallon, with a filter and light, and have added Jungle, Tank Buddies, Fungus Clear. Although I don't know what it could do to help. What co
uld this be and is there a cure? Any reason why this would happen?
Ammonia Level: 0
Nitrite Level? : .1
Ph Level? : around 7.5
Tank size(How many Gals) and How long has it been running?: 20 gallon, a year and a few months
What kind of Filtration?: Aqua Clear 150
How often do you change the water and how much? : every week or two, 40%
What kind of Water additives or conditioners?: none, just to the hospital tank the medicine
Any Medications add to the tank? : To the hospital tank, Jungle
How many fish in the tank and there size? : 1 tiny bottom feeder, 1 sarasa comet 1 1/2 inch, and the 2 sailfin mollies 2 inches or less.
Add any new fish to the tank?
What do you feed your fish?: Goldfish Flakes, Goldfish Green Pellets (hardly ever feed this), Betta pellets (almost never feed), Sprila, and I just bought today some Tropical Flakes
Any unusual findings on the fish? Such as
"grains of salt", bloody streaks, frayed fins, fungus? : explained above
Any unusual behavior? Like staying
at the bottom, not eating, ect..?: swimming normally, eating fine so far
If anyone can help, it would be much appricated, thank you.

The gold fish is a cold water fish and shouldnt be mixed with the tropicals Mollies require salt they are a brackish fish. Try giving your mollie a salt dip and see if that helps. You shouldnt have any nitrites at all. Do you know why that is up. I dont mean to sound like a smart rump. Because believe me I dont want to be one. That is just my opinion.

Thank you for your reply Angel_lady! Lovley ferret on your icon! It is a ferret?

I know about fish, so I'm not a beginner, just to let you know. It probably sounds like I"M (not you - don't worry) being the smart "'rump'" or rude but to inform you. I have been fish keeping for about 6-7 years now. That mostly consists of goldfish keeping. I have made mistakes. I am not afraid to admit that.

I agree that mollies (are tropical) should not be with goldfish. I do have a heater, but I don't feel like I need to use it - my tanks are all around 73 degrees ferigheight. And I'm always afraid of what could happen - what have happened to many of my friends - that the heater could fail and the temp. go down to quickly or it might malfunction and boil my fish alive.

Bacially I think that the tropical and goldfish don't go together because of their tolerences. Goldfish are high producers of waste and can tolerate a fair amount of ammonia/nitrite. Tropical fish can't tolerate it as much as goldfish can. (sorry if I sound like I am critisizing). Goldfish can live with tropicals. But I learned that Tropical Fish can not live with Goldfish very happlily and won't be living in a healthy environment for them.

I added non-idionized fine sea salt to the five gallon (with Moka) today after a small water change.

Angel died (my other sailfin molly), thinking she was perfectly healthy when I looked at her that morning, last night.

After she died, I quickly did a water change in the 20 gallon Angel was living in with Fin (sarasa comet goldfish) and Dojo (tiny bottom feeder). I think the nitrites are back down to 0 now.
