Neon Tetra Disease

[Peternub]

is this neon tetra disease ? one die so far?
there like a light brown stripe on a part of the red tail of the neons

 

[WILDER]

That neons in bad shape.

Size of tank in gallons or litres.
How many fish and which type.
Water stats in ammonia, nitrite, nitrate, and ph.

Does the brown on the fish look fluffy, or like rusty coloured varnish.
Any signs of flicking and rubbing, darting, erratic swimming, laboured breathing.


Signs of ntd are.
Red stripe area will look bleached out, or a milky substance on red stripe area.
Sometimes ntd can also start off as bleached patches on the tail part.
Sometimes the blue area on the fish will turn yellow.
Sometimes there will be black linning around the red.
Fish will lose weight.
Bent spine sometimes.
Lumps on the belly.
Swimming in an odd manor.
Fish will leave the shoal and act restless.
Later stages, popeye, and dropsy.

I had ntd in my tank about 5 years ago, and when I saw the brown reminded me of it.
The neons all showed different symtoms
But I would need to see more of the above symtoms to definately say ntd.
