Bent Nenon Tetra

[[email protected]]

I have a pair of Neon Tetras in my tank for about 6 months. They have
both grown considerably and they appear to be healthy except for one
of them seems to be "bent" behind his belly. Its body does not run
straight anymore. Right behind its belly the body has a distinct bend
that goes out and then comes back again.

He seems otherwise normal. The tank has 2 clown loaches, a pleco, 2
guppies, and the two neons. Has anyone seen anything like this
before? Is this the "Neon Tetra disease"? If so, will it affect any
of the other fish?

I've had several Neons develop this bend. It hasn't jumped to other
fish. I try to keep Neons in the six to twelve range which seems to
be a good sized school. Two seems like a small number for a neon
school.

I have a of Guppy like this. I have always assumed I jammed it behind a
breeding box and damaged it.

Scolosis and other skeletal deformities generally have 4 possible
causes:

1. Injury
2. Systematic infection (like Mycobacteriosis)
3. Chronic environmental deficiencies (bad diet, high nitrates, etc.)
4. Genetic deformities resulting from excessive inbreeding or simply
"bad genes."

Test your water, make sure there aren't any problems. Neons aren't
picky about diet, so I'd rule that out (unless you've been feeding it
cheesburgers or something) something like Mycobacteriosis is possible,
and I find injury somewhat hard to believe unless you caused it (neons
tetras really aren't active enough to injure themselves readily).

Beyond that, there really is nothing you can do. It is likely an
individual problem.
