A few months ago, i purchased a 20 gallon tank for my kids to enjoy, plus me. I got two glofish and 2 dalmation mollies. One of the mollies was pregnant when I purchased her, and i ended up getting a breeder net. Well she gave birth to the fry, and I then took her from the net. The male molly passed about 5 days after the fry came. Then within 3 days the female mollie died. After about a week all the fry, who seemed fine had died. I took a water sample to my pet store and my nitrates were extrmely elevated. Luckily, my glofish made it. I was told that when the fry(20 of them) were born it was just too many fish for my 20 gallon tank.

I didn't add any fish and waited about a week after I got the water right, and added 2 platys and a pleco. My tank had alot of algae, and as soon as i put the platys and pleco in the platys went to work and my tank is now spotless. I was told both platys were male, b/c I didn't want to loose any more fish. Well I think they were wrong and now my platy has a swollen belly. I checked on line about determinging sex in platys and sure enough the preggo looking one is female.

Here's my question...I have a small 2.5 gallon tank, and want to know if i should allow her to give birth in my main tank or move her to the small tank until she has the fry?

I'd suggest waiting until she gives birth, then transfer any fry you see to the 2.5 gallon using the floating bag method so to not shock them. They are born with an egg sac, wait until this has been completely utilized (about three days) and then begin to feed powdered flake food, which is easily attainable from the pet store.
