Neon Tetra With Large White Lump On Side Of Mouth

[jeanne-marie]

Hi!! I hope someone might be able to help me. I've had my tropical tank up and running for 4 weeks. 215 litres, aquaone 980. I added 6 neon tetras but within a week one of them had what looked like a small fluffy spot on his nose. It had appeared within a few hours. I monitored it for a few days and when it didn't appear to go away I was advised it sounded fungal and to treat the tank with eSHa 2000 Fungus, Funrot and bacteria treatment. I ran three days of treatment a week ago. It is even larger now and looks like a big white blob sticking out from the side of his mouth. It hasn't spread around the bottom or around to the other side but is now starting to go back around the edges. He seems fine, swimming about, eating well and keeping his colour. The lump does not resemble cotton wool.

I have tried to take a picture but the quality is really poor. You can make it out in a video though!

Tank is running fine, I have the water tested twice a week at my local fish shop.

I would be very grateful for any advice as I would hate to lose one of my first inhabitants!

Many thanks

Sorry, typo in question above, I meant it's turning black around the edges now!

neons are sensitive fish and should not be added to tanks of less than 6 months in age,

water stats will help.

Thanks the quick response!

I only have a strip testing kit which seems to be a bit vague with just colour codes and a wide range between some but I will give you the stats:

GH is between 30 - 60
KH - 0 - 40 but nearer to the zero colour
PH 6.5 - 7
Nitrite - 0 - 0.5
Nitrate - approx halfway between 0 - 20

As I said, I do have it tested at the aquarium shop twice weekly - last test was Sunday.

I had no idea about Neons, I was advised by two different sources to put them in first!

there should be no nitrite reading so perform a WC, and neons are the worst fish to put into a new setup
