Ok well what I was thinking was that some plants dont like other plants. For instance - I know that Daffodils will kill Tulips if you plant them near each other in your garden. And I have heard of people having similar reactions in their planted tanks, but I cannot remember the circumstances. I remember the word for it was "allatrophic" or something like that - but I couldn't get the spelling close enough to search for it here in the forum.
This was only a question of curiosity. I wasn't trying to troubleshoot a problem in my tank - if the water was old enough to make something like this happen, I think the fish would be dead... :-)
