Sick neon tetra losing colors

Sorry guys first time fish owner, I’ve had some neon tetras for over three months with no issues until last week when I woke to find one had suddenly passed away. Now tonight I have noticed another one has lost part of its colouring and has some white spots (see attached). It’s still schooling with the others but seems to be taking far more breaths and didn’t eat any food. Iam thinking it looks like neon tetra disease or something similar. There are no other fish in the tank other than the neon tetras. Does the photo look like this could be the case? And if so should I go straight to euthanise? The others look fine so far but really worried Iam going to lose them all now

Welcome to fishlore I have a few questions

How many tetras are in the tank?
I see starfish in there is it live?
Starfish can only live in saltwater so that could be a salt water tank which is not good for tetras.
Did you add any new fish/decor in it?
how often do you do waterchanges?

There was six tetras but down to five now. I’ve never introduced any additional fish and the decor has been unchanged from day one The starfish is also just ornamental and I do a 20-25% water change weekly

hmm Im not an expert at this. It sounds like neon tetra dieses but im not 100% sure. It also might be high amoina and nitriate. Have you tested recently? It does sound like the first stages of this.

 

Hi there, welcome to Fishlore! I recommend you fill out an emergency template form and paste it here. It will allow us members to give you better advice and possibly pinpoint what is happening to your Tetra.

 

This is typical of Columnaris, a bacterium that lives on the fish's skin without harm but can attack the living tissues of the fish if the immune system stops working properly.

Some strains of the bacterium are thought to be more specialised or virulent than others. Columnaris on Neons seems to be specific to Neons.

Suppression of the immune system is usually because of some other problem leading to stress (e.g. some aspect of water quality) which in turn leads to the fish not being able to fight the disease off.

Neon Tetra Disease is rare but has similar symptoms.

The reason that affected fish breath quickly is the Columnaris attacks the gills. The reason the colour of the fish is affected is the Columnaris attacks the muscle tissues of the fish.

To figure out why the fish are coming down after three months of relative health we would need the info requested.

Agree.

BTW the article in the link is the first one with pretty quality info about real NTD !

Temp of 26C too high, need 20 - 23C.

Neons need very little food (half a flake each per day). Ensure no food is left and spoiling water quality. Something has happened to bring on the disease. Work this out.

Have a few different quality foods.

Gentle current and some surface disturbance for aeration.

Plants for security.

Soft rather than hard water (I use 50% rainwater).

All I can say without seeing the tank.

 

26C is definitely not too high for neons.

The only concern I have is the presence of nitrites. Any ammonia or nitrites is bad for fish. Could be due to overfeeding or some other cause (eg ammonia in tap water).

 

Temperature: 21 – 25 °C

Paracheirodon innesi – Neon Tetra (Hyphessobrycon innesi, Cheirodon innesi) — Seriously Fish

That's where I get my info from.

With my own fish, there was a lot more aggression from the males at warmer temperatures.

Fish experts such as Ivan Mikolji have said that the temperatures he measured where Neons live is lower than expected due to the shading of the jungle streams by foliage.

Think that might count for a lot of species.
