I just bought 3 mollies today from pet smart. My husband and I went out to dinner and came home to find that one of them had given birth to 5 babies. I can't tell the difference between male and female and have NO idea how to care for them. Can someone PLEASE help. I will check back here for any answers or feel free to email me at stoomey93@gmail.com

    If you look at the molly page on Animal World you will see the top picture(Silver Lyretail Molly) look at botton fin near anus. Thats a female. Now look at the third picture(Silver Balloon Molly), thats a male.

    You can tell if it's a male or female by the anal fin. The male
    will look like a flat hook and the female like regular fishes.

    Yep, that's enough.

    Keep it as it is because if there are more males they fight. More females and if there is strong male it is easy for breeding

HELP!!!! I recently bought 4 silver mollies. They are in a 55gal tank with 2 plecos, 7 catfish, 3 alge eaters and 4 swordtails. Less then a week after I brought them home, I noticed one had a big belly and a gravid spot. A little bit later..we had babies. This was fine with me. Two weeks later...we had MORE babies. Now - I just noticed EVEN MORE babies. They all appear to have a rounded anal fin. None of them appear to be males - who is getting them pregnant? Do I have the Immaculate Concepcion of the fish world???

    I think there must be a male but you don't need a male for females to lay eggs - but I am not sure about fish. You need another tank - 55 gallons is too small for 7 catfish, 2 plecos, e alge eaters and 4 mollies and 4 swortails. Rule of thumb every one each of adult fish needs one gallon of water. You need to separate out the fish in the tank as they are going to get agressive on each other (or stress or ill). You also need a tank for babies cuz the bigger fish are going to see food when the fry swim. Immaculate conception - probably not but stuff happens. Good luck and have fun.

    Mollies and other livebearing fish are almost always pregnant when you get them. They can also get pregnant w/ a male and then get removed to an all girl tank and they will continue to have babies about once a month for a few months! Yes, they only have to do it once! Also they are closely related to platys and swords...I think they can procreate w/these. My surprise comes from all your fish NOT eating most of these babies/fry and leaving you w/10 or less each batch...natural selection in their world! Why haven't your other fish helped a bit?

Please help, input appreciated:
I have a creamcicle Lyretail Molly that is laying down on the bottom of my 20g tank. He has done this MANY times before, but somehow has recovered from being, what I was conviced was, dead. The first time I noticed his deteriorating condition, he appeared to have not-so-good looking fins, and a little bit flakey, definitely frail. However, he recovered and started to look better. Now, he's back to where he was. Literally laying on the gravel (still moving the tiniest bit though!). I just fed my fish and, surprisingly, he came up to eat. So, any suggestions as to what I should do? Want to help him, but don't want this to continue, obviously. I have a 20g freshwater tank, all conditions I'm pretty sure are normal, because my red wag platy, sunset platy, dalmation molly, and other lyretail are all doing perfectly fine. I also have 4 baby platies that are doing great. One more thing- my three mollies (all boys) are fighting frequently, ugh, bad boys... could he keep getting injured from fights? thanks so much for responses!

Is it "natural" for a lyre tale molly to have his back tail in more of a "closed" position? My other mollys haven't done that.

    When you state 'closed' position, what exactly are you referring to?

My platy looks like she will burst. Her scales are actually sticking out and not laying down, she is so pregnant. Is it possible she can't get babies out? She now sits on bottom of tank and wouldn't move if it wasn't for my cleaner fish bothering her. She is so big she hasn't gone to the top to eat now for 2 feedings. Is she o.k? Should I do anything to help her or will that stress her out more?

    Mary, I'm a beginner as far as fish keeping but your description makes me wonder if she had contracted dropsy. Please update and let us know how she is doing!
  • Alex Burleson - 2011-10-15
    From the description, your platy sounds as if she has a common aquarium disease called, dropsy. Symptoms of dropsy include protruding scales, unwilling to eat, and lying at the bottom of an aquarium. If I am correct, you should begin treatment as soon as possible. Treatment could include using the following medicines including but not limited to: API™ MelaFix® Antibacterial Fish Remedy, and Maracyn Plus Biospheres AntiBacteria Therapy from Mardel. These can be purchased at many local fish stores like PetSmart, or Petco, and possibly Walmart.

This is more of a question than a comment... I have just recently gotten an albino molly and I had decided to pair it with an albino cory... They seemed to get along at first but just today I noticed the cory had what looked like an injury on his head. It doesn't look too bad and he seems ok otherwise but I separated them immediately. Would a molly hurt a cory like that? I read up on both of them and it seemed like they would be alright, but I am a beginner. I'm keeping them apart in any case I think. Is it ok to have a cory alone? Hope there are some answers. --thanks

    Both the cory and the molly are supposed to be good community fish. They should get along without problems. I have included an article on Fish Diseases and Treaments just in case there is a possible disease (fungus) going on. Good luck and let us know. OK?

We are having an issue with our mollies dying and are not sure why. We have 2 black mollies and a silver that we have had from the beginning that are alive and doing well. We have lost 1 silver molly, 1 dalmation, 2 plecostimus, and 1 guppy. Any suggestions?

    Hi paul,
    Here are some things you might want to check:
    water quality
    pH, dH, temperature
    some of your mollies may be aggressive and are killing the other fish
    I hope this helped you a bit.

    Dr. Jungle would say, 'Why did Molly get a Molly named Molly?'. The more Mollies the Merrier!
