overstocked?

[Annastasia]

what exactly will the gravid spot look like? the female guppy has a sort of black spot on her rear belly, but it looks like it is below the skin--hard to describe please desribe in as much detail as you can the appearance of the gravid spot on pregnant fish

how big do mollies get? mine are between approx. 1.8 inches and 2.25 inches, the male being the second largest

do mollies do as well in freshwater as they do in brackish? Is it a good environment for them> Will they be healthy and happy in completely fresh water?

sorry for all the questions but am just trying to gather insight
thanks

As Cheekeyarab already said, the gravid spot is the eyes of the fry. It looks like a black /brownish spot under the skin. So it sounds like your guppy is pregnant, which is VERY likely if you have a male and female in the tank together!

Mollies get to about 3", I believe. Females are usually bigger then the males, once they are full grown.

They do okay in fresh water. I've had them in completely fresh water, and they lived for a long time. Sometimes they DO like a little salt in the water, but it not nessecary.
