White fluff on a fin and a tail

Hey guys, I'm new to aquarium keeping, so I have no idea what it is, but it sure looks a bit out of place and it wasn't there yesterday.

Today I've noticed a white fluff on my rainbowfish's fin and tail, here is the picture:


It doesn't look like just something stuck to it by accident. This got me worried as I have other fish in the aquarium too, they seem to be alight, but neither the less, is this a disease, can it be treated?

Hmm. Looking at the pic, it's clearly a white spot of some sort.
If it looks fluffy in person, fluffy is fungus 99% of the time.

Most likely caused by some kind of injury... Fungi rarely infect healthy tissue.
You're gonna need to get an anti-fungal, but first, can you give us your water parameters and tell us what fish you have?

(I'm not the most authoratative person on here, so wait for a second opinion- don't jump out to buy an antifungal if you could possibly use salt or some other treatment. If you do decide you need one, I keep pimafix on hand.)

I have 4 cherry barbs, red-line torpedo barb, 1 pleco 1 raphale catfish and this rainbow fish. I will get my water testing kit out tomorrow, so I'll tell you my parameters.
Is it contagious?

Here's the water test results:

PH - 7.2
Ammonia - 1
Nitrate (NO2) - 0.50
Nitrate (NO3) - 60

That looks like the same thing that nearly wiped out my entire aquarium. I used an antifungal and it finally passed, but not before taking literally over half of my fish with it. Was very frustrating. Wait for a diagnosis from someone on here who may be more knowledgeable though.

Also, I would suggest a water change with those ammonia/nitrite/nitrate readings.

Should I separate the fish? I don't have an extra tank, but I can find some space for her.

Like I said, you may want to wait until you get a diagnosis from someone more experienced. If it is the same infection that I had in my tank, it is very very contagious...

Personally, if I ever encounter those white patches again, I'll immediately quarantine the fish.

The rainbow fish has now been quarantined. I'm going to try to cure her in a separate bowl now.
What would be the next best prophylaxis, preventative measures?

Some more info:

It's a 72 litre tank, I just bough it with the fish about a week ago with a tank form a neighbour, I fillied it up withitioned water, and allowed the fish sit in a bag for 2-3 hours. I never had a chance to cycle it as this is the only tank and I had to import the fishes.

  • As stated above fish included: 4 cherry barbs, 1 red-line torpedo barb, 1 pleco, 1 Striped Raphael (Talking) Catfish and this ill rainbow fish.
  • The tank is un-planted, with 2 logs and gravel bottom.
  • The tank is running at the room temperature, as I'm still waiting for heater to be delivered.
  • I am using a sponge jewel pump and filter.
  • I have washed the filter/ sponge and done about 40% water change after the fish has been quarantined.

Rainbow fish was healthy for about 5 days, that's how long I had her before I bough it from a neighbour, and I've noticed the fluff on her yesterday.

I'm almost afraid to ask... what did you "quarantine" the rainbowfish to? With the fish you list, you really really want a heater in that tank... And I think that the pleco and the raphael catfish are both going to be far too large for your tank. 72 litres = 19 gallons.

According to Aqadvisor - Your aquarium stocking level is 181%.

And that is without the rainbowfish.

Not to worry dude, the rainbow fish went to a neighbour's 25 litre bucket.
Btw. that calculator is nonsense, according to it, my 4 cherry barbs + 1 pleco = Your aquarium stocking level is 182%. That's nonsense or I am just new to this?
