Thanks to all who welcomed me. This is great! My 40 mollies included babies, some of which I have given away to new homes. Now I only have about 30 and will get rid of about 15 more. My momma mollie just died. She was all blown up/inflated like a balloon. I thought she was pregnant again, but she started swimming funny and stayed on the bottom most of the time. She quit eating and died a few days later. I guess she had a swim bladder problem, but I am new at this so I do not really know. All the other fish seem healthy. One of my guppies is pregnant and getting large--I am so excited!
