Problem with neons help

[Tazman12]

Just got about 7 neons yesterday for a newer 10 gallon tank.

This tank is only about 2 weeks old but it has been running filter media from an established tank.

I have noticed that there under belly looks quite large.( Not all of them maybe 4 out of 7)

Not quite sure what may be the problem can anyone help.

Thanks

That's pretty normal. As long as they look and act fine, don't worry about. Mine did that for a while when I first got them. You could try not feeding them as much?
