Fungus on new fish!

[BLUE FIN]

I bought some Platties yesterday afternoon and all seemed well, however i have been looking at them today and have noticed that the male has white cotton coming from his mouth, I'm assuming this is fungus?

My question is do i treat the fish myself or take it back and explain what i have found? This is the second major problem with this shop, the last was a very pregnant molly which died a couple of hours after it was bought home also another thing i have noticed is a large amount of dead fish in the tanks! The owner of the shop is a member of OATA and this is why i shop there but i am now very unsure.

Any advice would be appreciated.

Do you know if they would take the fish back?
If you're not sure, I would go there or call them and tell them about the situation. Don't bring the fish back if you're not positive that they will take it back. This would cause a lot of stress on the fish being transported back and forth. Keep any new fish away from your other fish. Some people do this for a few weeks to help prevent diseases from spreading. I would move this one way from the others though. Keep your eye on the other new platys also. They may get the same disease as this one. It does sound like fungus to me. I have a platy that has fungus on the tail but I have been treating it and the fungus seems to be going away.
Don't buy any more fish from these people again. Also, in the future, if you see dead fish in the tanks, don't buy any fish from that store.
I am sure someone else will give you better advice. I am not an expert.

I had a similar problem with 3 harlequins

One of them within 2 hours of my putting them in my main tank, had a white fungus on it fin.

I lost all 3 over the next couple of days, and then lost my long standing Harlequins within 3 days.

I found out that fungus is present in all tanks, and that a fish can be hurt while been netting, I think this is what happen to the first one. The rest died because I was not de chlorinate my tap water. and the harlequins were more susceptible to the poor water condition which resulted.

White fungus is the result of the fish not been able to defend itself or the fish has been wounded. and cold water will not help the situation.

The positive news is that fungus to very very treatable – I had successfully that’s to this forum treated a red tailed shark and a very old angle – many thanks all

Just to update: I thought the problem had gone as i couldn't see the cotton anymore, however i have just noticed it on two of the other platties (same place in the mouth) so what is best to use? I have some Protozine but will this effect the water conditions IE: good bacteria? If this isn't the best med to use then what are my options?
