I do not want to deal with babies! I'm wondering if it's OK to keep a group of all males.
Actually, in the few years I've been breeding mollies...Bachelor groups actually do pretty well without females to fight over.
It depends on space and hiding. Those are the two biggest things. Say you want five boys...you will want at least a 25+ gallon tank, bigger is better, with a lot of plants and caves. If you can get a 30 gallon that'd be about perfect for five boys and some cories, kuhli loaches or other small, peaceful bottom-dwellers. You want at least 5-8 gallons per fish as a bare minimum, if they don't have the space, they may fight for it. Same if you had girls too, but it'll be worse with boys if you don't have the space. With proper space they wont fight so hard, many think with less space they wont fight as hard because they don't have room to do so, but this is false with mollies. The only time I ever had so much trouble with sparring males was when I QT'd three in a ten gallon for two weeks, right away fight, fight, fight, plus their bioload is very high and they don't go well in small spaces. I used my twenty gallon as my QT after and had no issues with that! lol I've rarely had issues with males anyways, it's females I tend to get aggression issues with...
There may be sparring, it happens. Boys will be boys, but without females to chase, their spars will likely be...half-er...yeah, they wont go full force. lol Why risk injury without any benefits? Fish aren't as dumb as people think...though there are that special...many. LOL
Anyways, yeah, a bachelor group should do just fine. You may have a problem male or two, and you'll want to remove those. Any who rip fins, you want them out or it actually could start a mess. But in all likelihood, they will just do mini-spars and get along alright, may even try to mate with each other(if that happens don't be fooled unless you're unsure if you really do have all males), since livebearers are always trying to mate, even out of species or with other males.
Your "Dominant female" is telling the other that there is not enough space there, she'll die if you don't do something.When are they NOT in heat??? Maybe when delivering the babies? Males after them ALL the time!!!
I know my 20G is too small for much, but I do have 6 Mollies, 3" and 1.5", 4 females, 2 males. (was 6 females, but took 2 out). Two had babies, so were put into another tank. I can see that the Alpha male, Sailfin GoldDust/orange with green sparkly fins, who is extremely aggressive, is the head fish. He is the dominant one, keeps the other one hiding. So I probably will get many orange fish from him, as the other one tries to go to a female, and is chased away by the orange male. He is a handsome one, so no problems there. But having bred birds once upon a time, I can tell a dominant one for sure.
I think if I had a larger tank, there wouldn't be any sparring, but for a small tank, you have to live with the extra cleaning and heavy bioload to keep the water sparkling. It is clear now, and all the 10G tanks, too. Never had a problem with the 10G tanks, once I learned what cycling is, and how to do it. Thank you for all the tips, and I am getting better at it now.
:lol:
I have read that the inferior males get a chance to breed with the female if they do that ..for some reason the female gets turned on by this homosexual behavior which makes them bi sexual ..I read they can also change sex.Aggressive or playing?
So I am new to this forum thing. But I need some advice. I have 3 adult male mollies, 1 adult female, and 7 fry that I just moved from the nursery to "adult" tank. My male mollies keep chasing and nipping each other bottoms fin ( what I called their "private parts") is this normal? All 3 of them do it. But mostly the salvation and silver gaining up on the black one.
