for a little while you will have to do water changes offten it is always a good idea to have a filter for any fish
My filter was not working for 2 weeks my mollies(babies) are still fat and happy.
Mollies are live-bearers, which mean the majority reproduce by giving birth to live babies.
NO!
Yes they are.
NO!
I would say a bubble nest yet mollies are live berriers are they real mollies then?
Yes. A goldfish can live without a filter. They may not live as long, but they do not have to have a filter, or a heater. I had goldfish in a five gallon tank without a filter for a long time. Hope that this helps.
Not normally.
no
Mollies actually give birth to live young, they are one of the few tropical fish species who do this.
Not live ones!
Some mollies die after giving birth due to the stress of it, but it is usually rare. most mollies survive.
I don't recommend it. Mollies can get larger than a Betta (Siamese Fighting Fish) and be far more bullish than a Betta. A Betta could easily get beaten up by Mollies! Mollies need a minimum of 20 US gallons anyway.
