Neon Tetra Disease?

[MrWalker]

I recently bought an aquiarum (less than two weeks ago) and I've noticed that some of the neon tetras that came with it have a peculiar shape. I haven't noticed any of them having the white bleached spots that are typical to the NTD, but I have noticed some to have lumps, one to be very "skinny" and "bony", and one to have a hunch back. Can anyone please take a look at the accompanying photos and help me decide if this is NTD or something else?

Thanks for your expert help!

Worried regards,

To me they appear to be deformed rather than diseased. They have nice color which they wouldn't have with NTD.

I agree, the colors seem much more vivid than I have seen with NTD. Dulling of colors and then a distinct desire to "hide" and "be alone" seem to be the calling cards I have seen with NTD. Some might have lumps/lesions or deformed spine, but they don't have the consistancy that the dull or complete removal of color plus removal from the school seems to have.

Thank you for your input, both of you!
The fishes have been living like this for more than two weeks in my care, and I guess they have lived quite a while before I took over the fish tank, too. As you mention, there are no white patches and spots, this is why I was puzzled, too. The colors are a little faded on some of them, where the red is slightly more towards orange, but the blue areas are nice and vivid on all of them. There is definitely no desire in them to hide, the "hump back" is fighting hard for his food and is not "shy" as compared to his compadres.
The small one is a little more careful, but he too is eating. And they are both "in the pack" with the others, they aren't hiding away and "sitting in a corner".

Well, I will keep my eyes on them Thanks again for your time and input, it's much appreciated!

Picture two looks like a female with a load of eggs. That should change every few days if it is eggs.

Pictures one and three look like the tail section is deformed.
If they are all eating well, I'd not worry too much, but I'd not spend money on new fish for a while.
