Mouth Rot? :( Which Medication?

[Melava87]

Hi all

I have a new ish cycled tank which currently has stable ammonia, ph, nitrates and nitrites levels.

Fish seem happy and are feeding well.

All except one - my female mollie was bought from pet shop Friday and took an instant shine to my male. They appeared to be best friends and swam around happily together for days.

However the past 2 days she has been shy and reclusive and has say with her mouth against the heater in the corner. She now appears to have what looks like mouth rot / cotton wool mouth

I have just rushed out (with my 5 year old in her jammies ready for bed haha) and bought API Melafix, API Pimafix and API aquarium salts.

Which do I use?

Can I use them simultaneously?

I plan to do a partial 50% water change tonight so will treat the tank afterwards.

Will the treatment affect my other healthy fish?

And how do I use them exactly?

Sorry for the 100 questions I just don't want to lose them.

Thanks

Melissa

I feel so sorry for UK fish lkeeprs and meds which are so hard to get over there.
 

 
Mouth Fungus

   Symptoms: White cottony patches around the mouth.
 
   Mouth Fungus is so called because it looks like a fungus attack of the mouth. It is actually caused from the bacterium Chondrococcus columnaris. It shows up first as a gray or white line around the lips and later as short tufts sprouting from the mouth like fungus. The toxins produced and the inability to eat will be fatal unless treated at an early stage. This bacteria is often accompanied by a second infection of an Aeromonas bacteria.
 
   Penicillin at 10,000 units per liter is a very effective treatment. Treat with a second dose in two days. Or use chloromycetin, 10 to 20 mg per liter, with a second dose in two days. Other antibiotics can also be effective. Kanacyn (kanamycin) will treat both bacteria at once. Maracyn (erythromycin) is effective against C. columnaris, and using Maracyn 2 (minocycline) in conjuntion with it will treat the Aeromonas bacteria as well.
