well, goldfish don't need a heater, so if they can live with a goldfish, then yes, they shouldn't need a heater. I'm gonna try to put a couple mollies (maybe like 2, or 3) in with a goldfish. they "would" be in a, um, I think it's a 1 gallon tank, that has an air bubble filter, thing, that goes in at the bottom of the tank, and it also has a hood, with a light.... You should try it, cause you never know what nature will bring you! Have fun! :):):)
Silver Mollies need fresh water
they don't need it ,but they prefer it.
none because mollies need 5gallons and up
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.
As Mollies are tropical fish, they need regulated heat and good filtration. My Mollies have been known to dive.
They may be too crowded. I have heard that mollies need 2-3 gallons per fish. My daughter's male dalmatian Mollie keeps nipping at the female and has killed 2 so far.
Yes, Mollies have scales.
Mollies need more space than 20 litres. With the number of babies that have been born, you now need at least 115 litres for your fish.
Might be time to get a tank divider to separate them. Although, typically, mollies don't eat tetras usually unless they are fry.
Members of Poecillidae, mollies included, only eat each other if the others are babies, or dead. But most likely, he jumped out.
Mollies can be kept in quite small aquariums; probably down to about 5 gallons in size as the absolute minimum.
yes mollies east my armpit too x
