The water near the surface will be more oxygenated, be more (or less)
turbulent, and possibly closer to your air temperature, so:
i) the oxygen levels are too low
ii) their gills are damaged, so they seek locations with higher O2 levels
iii) the water is too warm (or cold?)
iv) the water there is of a turbulence (or amount of predator activity)
which is more to their taste
v) certain illnesses can attack the gills or stress the fish to produce
these symptoms

If they went through an ammonia cycle, then ii) is likely, if the other
causes are ruled out. jmo hth

Danny,
It would be helpful if you could provide some information about the tank,
such as:
How long has the tank been up and running?
How long have the fish been in it?
Temperature?
pH, ammonia, nitrite levels? (also, "normal" provides an idea but numbers
help beter)
Filtration type?

When it comes to unhealthy and/or dying fish, these basic kinds of
information can provide a wealth of background for others to help diagnose
potential problems.

Nevertheless, NetMax has a quick list of potential causes. NetMax is one of
the great ones on this forum and you're sure to get reliable advice.

Hi Danny. My platies do that a lot too, I am thinking it is just
something they like to do. They will hang up there for what seems
like a long time, but also then hang around down in the water, and
swim around. They have been doing it for the four months I have had
the tank set up. So it could be nothing to worry about. I have six
types of fish in the tank, and none of the others ever do that, just
the platies. If you watch closely you can see air bubbles coming out
of their gills when they are up there. I have month-or-so old platy
fry also, so I would think if there was a problem with the water they
would not be growing like weeds.

Good point. That's another possibility. Mollies are known to eat the
protein layer which naturally occurs along the water's surface, and
Mollies are very closely related to Guppies. I wouldn't be surprised if
Platys and Swordtails do the same thing.

One of the ways to distinguish is to watch the fish to get their pattern.
Low O2 is worse in the early morning, or when the tank water is at its
warmest. Also low O2 tends to affect fish by species and size, at mostly
the same time. If your water parameters check out, they are eating and
colourful, the abdomen has the proper shape, and their respiration seems
normal, then surface 'snacking' would be a very good possibility. I hope
that's it.

well thanks every one,
ive found out why the mother platy was doing that

talking about in my first post are getting her markings and the fathers
colourings

the babys are swimming around happily and the tetras dont seem to
bother about them any more

thanks again,

Danny
