NO!
Yes they are.
NO!
I would say a bubble nest yet mollies are live berriers are they real mollies then?
Not normally.
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.
Mollies actually give birth to live young, they are one of the few tropical fish species who do this.
no
Not live ones!
A 20-gallon tank can comfortably house around 5 to 7 mollies.
Some mollies die after giving birth due to the stress of it, but it is usually rare. most mollies survive.
