White stuff on tetras tail :/

[Fishies86]

Hi, while doing a water change I've just noticed that some of my blue tetras have got White stuff on the base of their tails. It doesn't look fuzzy and I don't think it's loss of colour, but I could be wrong. I can't get a photo because they move too quick for my camera, but hopefully someone will recognise that and be able to help their behaviour doesn't seem to have changed, but I am worried please help!

Does it look like little pieces of salt? Or just discoloration? If it looks like salt I would think ich, but if it's just discoloration I would possibly think it's from your fish sitting next to the heater for to long

It's not ich. It doesn't look like it's just discoloured either. It looks like it's on their skin rather than in their skin (if that makes any sense at all ) it's kind of like a saddle over the very base of their tail, where it joins the body. They don't seem to ever go near the heater, and because of that an the positioning I wouldn't have thought it was re heater causing it.

Oh, I probably should have said. Am= 0, Ni= 0, Na= 10-20

Parameters look ok. Are the patches growing or remaining steady in size?

It doesn't look like they are growing at the moment, but I will be keeping a very close eye on them.

Just had a tetra die my water params are:
Ph-7.6
High range ph- 7.4 (why do they never match up?!)
Ammonia-0
Nitrite-0
Nitrate-5.

I had two fatter tetras and two thinner ones. It's one of the skinnies that's died.
The White patch on the other skinny does seem to be growing slightly, and the patches are starting to look slightly fuzzy, and kinda soft. All the other fish seem to be fine. One of my female guppies is being more aggressive than normal, but she seems to go through phases so I don't think it's related.
Sorry to revive the thread again but I'm worried :/

It seems like a fungus. Go to your lfs and get some primafix (spelling not sure) that should help with fungus

Ok, I will do that tomorrow. Thankyou do you know if that is ok to use with corys, ottos, and guppies too?

Yes, it's all natural so they should be ok. It's salt you have to look out for with them.
