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, 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 could this be and is there a cure? Any reason why this would happen?

Ammonia Level: Test tonight or tomorrow, thinking it might be too high because tropical fish don't tolerate that well. ?
Nitrite Level? : Test tonight or tomorrow
Ph Level? : Test tomorrow or tonight
Ph Level out of the Tap?: Test tomorrow or tonight
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 someone can help, it's much appricated. Thank you.

You should simply home the mollie in the 5 gallon, these 2 types of
fish don't go good togther diffrent temp,food,care,and plus
they stress out the fish.

I can't really help you there, i would simply quarantine the fish
until it goes away...Salt may help aswell...

i would do what black oranda said and get a anti fungal med, and a heater for the tank and you should be good to go

mollies need salt in water the same as goldies. Get some aqua salt and follow directions on packet. Start with the lowest and see how that goes.

Aquarium Salt? I don't think goldfish actually need salt but I will try some salt - not aquarium salt though, I hear that costs a lot - I think I will use on-idonized fine sea salt. And will house the two mollies together in the 5 gallon, when Moka gets better.
But I still need help with understanding what the diease on Moka is (it is a pinkish bubble near - above his mouth with whitish fuzz stuff on it - I've never seen this diease before) and if there is a cure?

I will add salt on my next water change. It might help.

Thank you!

hi jas.

while aquarium and seasalt are the same things, you should be wary of the size granules that your buying. in keeping with the dosage recommendations on aquarium salt packages, you need to try to find a seasalt that is close to the same granule size. otherwise, your actual salinity could be different than what you think youve got. this is because theres more actual salt per teaspoon of fine grade salt than there is in a teaspoon of a larger grained salt.

and for the mouth fungus that your mollie is suffering from, i believe a good antifungial medication is called for. otherwise it could very well spread and even (slight chance) that it could be passed to the other fish in the tank.

good luck and keep us posted!
