Vertical swimming

[Anandan Tanabalan]

I have recently added six White Cloud Mountain Minnows to my stable, cycled
'river' tank.

They were all quite sensible in quarantine and for the first day or so in
the main tank.
However, one of them (maybe just one of them at a time, as they very similar
to look at) has started some strange behaviour. This minnow swims quickly up
and down through the water column (18 inches).

None of the others seem stressed, & I have not detected a change in the
other inhabitants.

It usually does it the fast flowing water near the power heads.

Is this an odd symptom of disease? (no other visible signs, no
swelling/shrinking, growths or discolouration)

Or is it just odd-behaviour from a fish that ought to know better?

Easy to attribute human characteristics to it but I'm asking the group if
anyone's seen it before.

Thanks.
Tana.

Sorry but I forgot to say that at feeding time, the little fella swims
'normally' and gets food with the rest of the half-dozen.

Some of them also go for the sinking 'pleco' tablets that they didn't get in
quarantine.

I have noticed that my minnows all like to "play" in the faster current
from the filter output - fast up-and-down swimming included; I have
always assumed that it's normal behaviour from these fish. They seem to
enjoy the current.

Thanks for the reassurance, Sophie.

The minnows are now less inclined to do the up-down thing; I saw a couple of
them doing it at the same time though.

I am less worried that it's a bizarre swim-bladder problem or something.

I don't know what you mean by "water column," but lots of times my
fish up and down the glass. It is especially fun when they gather in
a corner and do this vertical schoaling. Sometimes it may be one fish
rather than the group. I am talking mixed species, not just one.

When I read the subject, I was curious. I have one Serapae that has a
swim bladder problem. She swims vertically all the time. I put her
in the quarantine tank and figured it would be easier on her, but
fully expecting her to die. She was quite poor at catching food
flakes. She has been this way for about 6 months now and has become
quite good at catching food even darting horizontally for a few
inches. Her body form has changed, elongated somewhat. I watch
amazed when I feed the community tank I finally returned her. She is
very competitive and seems destined to live a long life.

So, you can see, I had a quite different take on "Vertical swimming!"
