Deformed Fin And Red Colour Fading On Neon Tetra?

    I am currently cycling a 240 litre tank with neon tetras (which I explained in my other thread) and I am quite worried for my fish.
    I was watching them and one of the fishes has lost nearly all of its red colour and possibly a deformed fin, which another fish's fin looks similar.
    Is it possibly due to bad water conditions such as ammonia?
    Is the analfin deformed or is it just faeces coming out of the fish?
    Please reply as soon as possible.
    Thank you.

    What are the ammonia, nitrite, and nitrate levels? Did you detoxify the ammonia?

    A clearer picture might help for the analfin

    I don't have any test kits because I was expecting to do fishless cycle but the LFS employee said to do a cycle with fish, and he also said just bring the water to the store in a week.

    Well, if we don't know the ammonia levels, we won't know what's causing the stress.

    Does the LFS use test strips? If yes, they are inaccurate because the air can effect these strips, so liquid test kits is better to test.
