We have 3 female dalmatian mollies and a betta in a 10 Gallon. The larger of the dalmatians is extremely aggressive to the others, but seems to leave the betta alone. She never leaves the other two alone. Should I add a male or two? or what do you suggest to calm her down?

I am new to keeping fish and have two Gold Mollies, two Danios, a catfish, 3 Plato's, 4 Gourami's, a Cherry Barb, 3 Neon Tetra's and 3 Glow Tetra's. My question is concerning the Mollies. I get the impression, though I have NO experience, that the female is pregnant. The male keeps nudging her under her large belly. Do I need to place her in a birthing cage to save the fry when they are born?

Hello, my female black molly was hiding behind the air pump and all the other fish were going after her so I took her out and used the tank water in a gold fish bowl to put her in. When I stepped out of the room and came back low and behold there were little black babys everywhere, 43 of them! I saw her eat one and she was done. I put her back in the tank she's still hiding behind the air pump why is she hiding from the male? Because he's big and always chasing her. I have 2 white molliess the female is getting really round. What should I watch for when she is ready? I have a prago sunburst platy she can barely swim she's so round and very dark back end. How will I know when to get her out to save the babies? I have a very nice big nursery netted full of very tiny black molly babies atm.

I am from the philipppines. I got 50 fish tanks. I am breeding several types of mollies, all in one tanks. My only problem is that when a female mollies deliver its fry, all frys will only last for a week. No one will survive, and if there is, it is malnourished fry and got a very dull appearance. Can anyone fix my problem??

To whom it may concern,

Thank you for sharing your knowledge and expertise on mollies. I have learned much valuable information from your website. I have some mollies coexisting happily with other community fish including guppies, dwarf and Mickey Mouse platys, female bettas, one dwarf frog, and one double tail male betta. They all seem to be doing fine together. I have dalmation, orange and black regular tailed mollies. Recently I purchased some lyre tail mollies. They sure are an active fish. They constantly are speedy swimmers and aggressive breeders. I now have some babies from these fish and they are so cute! I have a silver male lyre tail molly that is often chasing the female fish. He is the stud of my tank so I call him Fabio. He is sometimes chasing the other males and I assume this is his way to get them away from his girl mollies. Luckily I have more females then males so no single female molly is singled out as that would lead to unnecessary stress. For later reference, I have organized your website and other related websites that I may need later.

I got red and black mollies which breed every 2 weeks. At one point I had 40 or more fry in my tank which totally amazed me and my girls. Lovely fish. Regards, Mossy

    How did you get the red mollies, did you breed them yourself...I'm want to try breeding to see if I can produce the red strain.

    Hi we have a nursery tank and at the moment, we have about 100 or more baby red mollies. She seems to breed all the time. Was wondering how to go about selling these fish as about 40 are all good size and we are scared they will start to eat the new babies soon. Thanks.

I have a short finned yellow molly. It is very small but lonely, and has no partners
except two gold fish, which I have.

I have 4 Mollies, 1 male and 3 female. I feel so sorry for the male because he has wanted to spawn for awhile now and the females aren't interested. He just looks so sad!
