Is My Neon Tetra Ok?

    Hi all,
    Posted this on the beginners forum but there was some differences of opinion. So thought I'd post here for a bit more advice...

    I have had my neons for about 18 months but my tank has been established for nearly 3 years. For the last couple of months I've noticed that one of them is a lot skinnier than the others. His behaviour isn't different but he did seem to find it difficult to eat bigger bits of food so I now make sure to crush flakes a bit. Should I be concerned or does he look ok? Thanks

    It is the fish in the middle at the bottom

    More pics...they're a bit blurrier though!

    My levels are fine 0 ammonia 0 Nitrites 40 nitrates (tap water has high nitrates).

    If your ammonia is not high then I’m gonna say that that is fin rot. No matter what it is, you should quarantine it because it could pass on the disease. You should treat it for fin rot and make sure that the water conditions are good.

    I don't think it's fin rot. It looks like your fish has a bent spine which could mean ther'e are other problems with it. What doe the fecal matter look like. Not eating or a thin fish could signify parasites.

    Its not fin rot, said fish has no fin damage, so thats out. The sunken stomach and not eating is pointing to parasites, what does the poop look like? Try to catch it and quarantine it.
