Mollies are just great! I'm only fifteen years of age, but have had Mollies for around 11 years. I recall that every time I bought mollies (pregnant as I have a keen eye for them), they would surely give birth the next day. Just last Christmas, I had three female Mollies which gave birth almost at the same time, and I have over 100 babies. Sadly though, all passed away, as I did not have the resources at hand. However, I'm trying now to leave the babies in the tank, it has been a week since their birth, and they're doing quite well. I have 8 Mollies and 10 Platies (very large ones). They mix well. Another thing, I would like to recommend the Molly to the beginner, as they're easy to breed and are great fun! Just yesterday, two were swimming in circles chasing each other's tails!

I have had a somewhat unusual experience with my most recent Molly's. My wife and I recently set up a new aquarium, and on my insistance, had 3 black Molly's included in the first set of fish to put in the new tank. Less than 1 month later, we have had no fewer than 5 deaths in the new tank, a Pleco, a Chinese Algae Eater, 2 Fancy Guppies and one of the 3 Molly's. Only now have I discovered the cause of this... virtually every fish in the tank is being pestered or nipped by the two remaining Molly's (1M, 1F). One of our Red Fantail Goldfish has severe injuries caused by near constant harrassment by the female Molly, including the loss of a fin and damage to it's beautiful tail. I have never heard of this happening before, I always thought Molly's were among the most peaceful fish you could have in any aquarium. We are now in the almost unbelieveable situation where we have had to section off part of the tank to keep the Molly's away from the other fish, until we get our second tank and transfer the Molly's into that one... I for one was very surprised by this behavior and think/hope it is the exception rather than the rule.

I have a trio of Mollies (two females and a single male) in my community tank with Swordtails and Neon Tetras and Rasboras. They keep very much to themselves, except that one of my females is "in love" with a male Gourami that lives in the tank. She sneaks away from her male and chases the poor Gourami around until the male Mollie chases her back into line. She can't understand why he isn't interested in her! They are a hoot to watch. The male is "King" of my tank, with his huge black sail and iridescent blue sheen. I love them! They are doing great even though our pH here is off the chart, more than 8. A very hardy fish.

I have Mollies and Mollies. They donīt practice birth control. I started with one 25 L tank and now have many more tanks *grin*. They are friendly fish and nibble at my fingers when I put my hand in to shift something about. I suspect they think I am lunch. I have noticed that male Mollies can be territorial. My Orange Lyretail Molly attacks and on two occasions killed off new additions. He doesnīt bother the juveniles that grew up in the tank, but any new male gets hell from him.

My Black Mollies had babies and sadly, all were eaten within the day. To be sure it wasn't going to happen again, I bought some Java Moss and some Cabomba and they work beautifully. The fry hide in them until they are old and big enough to come out.

I bought one black molly about 9 years ago. She had marbled babies. I keep them in a 40 liter aquarium and still have numerous descendents of the original fish. They continue to multiply. I do not remove the young, but give them plenty of cover, and a large number survive to adulthood and reproduce. The mollies are hardy, easy to care for, and do not harm my other fish. All of my other fish have since died (although they lived for many years after I got the mollies) and the mollies are the one fish that have continued to reproduce.
