About 10 days ago I introduced 4 female mollies to my figure 8 puffer tank. I got all females because I didn't want the sexual harassment or baby fish. Well several days ago one of the females had babies and I left them in and most have been picked off. I see two still in there and I've given them a place to hide around a powerhead they hang out behind. I've also decided that I want a couple mollies in every one of my tanks because they have been algae cleaning machines. I never had mollies before because I didn't really like them but I found some gold dust lyretails and fell in love with them. I'm thinking why buy more when I can get some freebees. Any way I've noticed another female looks like she's ready to give birth. She's huge but mostly she is running off all the other females and fairly aggresively. But she's doing this right in the open and the middle of the tank. Is this an indicator that she is gonna birth tonight? Should I go ahead and put her in a breeder? I've never had livebearers before but I've had some luck with bumblebee gobies and I had some celebese rainbow fish babies but they never made it to adulthood. I couldn't believe how large the molly fry are. Here's a vid. I had just turned an extra light on so it distracted her a bit. But she has the other females run off and runs them off when they come around. 55g /1.005 SG /F8 tankemate Thanks.
