My fav Danio...is she sick or pregnant?
 
A few weeks ago, I placed my danios into a new tank - I used the same "dirty" filter and even some of the water from the old tank. I let it cycle around for quite a few hours, then added them to the new tank. They were fine - then I noticed that my largest Danio was huge (as she would sometimes, then within a few days or so, she would be fine again). But now she has just stayed fat. The other Danios seem to be fine - my params are fine...I just wonder why she is so fat! BTW, I don't overfeed them :-).
Thanks for any suggestions.

Sounds like you may have Dropsy.

It could be, that the stress from being moved has caused her not to release her eggs. Be sure to keep a close eye on water quality in the new tank.
