This might have been covered here before, but I did a search and could not find it. My guppy (the same one I mentioned before who has had a stroke or something and is dying) had another batch of babies - for the second time in two months with no other fish in her tank! When I got her, she was pregnant and she had the babies and I managed to rescue most of them from her. But then a month later she had more and she ate them because I did not know she was pregnant again. Then today I was cleaning her little tank and there were about 10 dead babies in there, who were not there two days ago... I have never had this happen with my guppies before. Is this common???
