temperature/mollies

Question
Hi Renee. Do you know how to make the water temperature go down in a 7 gallon tank with 3 Mollies? And how do you tell if a silver molly is pregnant?( the current temperature is around 30 Celsius )

Answer
Hi Caleb,

That's probably too hot for your mollies, who should be around 80F.

I'd freeze a soda bottle and then would submerse it til the temp reaches the desired level.

I'd turn the heater down.

If it's being caused by a light, lift the light higher, off the tank and consider putting a fan nearby to keep the heat off the water.

If your molly is pregnant, you can tell by the plumpness of the stomach, but if it's a balloon molly, they always look pregnant, so you have to look at her vent area.  If you can see through her skin at all, and there is a large black pea in there, that is her uterus, and those are her developiing fry.  If you can't visibly tell, you can assume she is pregnant by those in her aquarium with her.  Are there other males?  Then she's pregnant.  They are extreme breeders.  

Be sure it's a female, not a male.  The male has a pointy fin at the bottom that's hard and rod-like, and the female's fin is normal.
