That certainly could be the case. The biggest one and the smallest
one seem to be doing fine, especially the 'big' one, but the two in
the middle have what I would call concave stomach areas. I know they
are eating at least some and currently they seem an energetic as the
others. I realized after my post that I am less concerned about this
being a 'disease' since they have been in a 20 g tank for 3 months or
so and it doesn't seem to affect two of them. Still I am not
certain. If no one sez to the contrary by Sat. I think I will just
walk on the wild side and relocate them.
Thanks for the response.
