Looks to be pregnate. If it was with any males it is pregnate or when you got it in a mixed tank most likely pregnate. I noticed with my guppies and or other livebearers that they get aggressive sometime a few days before they they give birth. They will chase the other fish away. Hide in one area of the tank or be by the heater a few days before. Just provide alot of plants live or fake at all levels floating and on the floor so that the babies can hide if you do not seperate the pregnate female and you want some of the babies to live in the same tank.Feed new babies crushed flake food that is a fine powder a few times a day. More water changes are needed if you are feeding more food and all are in the same tank.

thank you for your advice would you reccomend putting her in a breeding trap

No, I do not use those traps as they stress the females. I just put alot of cover for the fry to hide in the main tank. After the fry are born I net them out and put babies in a breeder net or breeder box til they get big enough to not fit in the biggest fishes mouth. Having a small 2 gal. tank with a heater is nice to raise the babies in also anything smaller you can not get a heater for.Walmart carries prest heaters for 2-5 gals and Foster and Smith aquatics on-line carries heaters for 2-7 gal. tanks I like the Theo heater as it has a light when it is on and a dial to select the temperture you like and shuts off when the water is low and is submersible. I sometimes have a tank set up just to put the pregnate female in to have her babies after she is done I take her out and put her in the main tank.You can tell when she looks skinny in size then before and you will see between 7-30+ babies. The older and bigger the female the more babies they have. This way she is not bothered by the males or other fish less stress.

thanks for your advice my neighbour as give me a 3 gallon tank with heater and filter ive cleaned it out and topped it up gonna leave to cycle for a few days then put her in there ill keep you updated with my progress once again thanks for the tips

You can use water from your existing tank to fill it and if you have a old filter cartridge you can seed the new filter box for the small tank with that. It will speed the cycle up or use some gravel or sand in a netting to put in the new tank. If the filter cartridge is dirty it has good bacteria and I sometimes will squeeze it into the new tank. I also use this stuff called Cycle to start new tanks. The filter and gravel is the cheapest way to get the new tank cycled faster. I have not lost any babies doing this. Just remember with many fry in a small tank you need to keep up with the water changes of about 20% once a week. The extra food will make the water bad. Baby livebearers are fun to watch grow up but remember that they will produce babies every 28-30 days and with you having 2 females thats a lot of babies. I keep the the babies from the previous month and let mine have theirs in the main tank. The bigger fish eat the excess babies. If not you will have so many tanks setup and it can be quite an overload to keep up with. I have 5 tanks with 1 QT tank. My main tank is a 55 gal. tank. smallest is a 3 gal. Cull the deformed babies you see. Get a magnifying glass at Staples for about $9 it's good to have to see the fry better and spot problems with illness.

hi i put her in seperate tank and 2 days later she gave birth to 8 but still looks just as big as before do they have there fry on intervals

I have platies that would have a couple here and there over a period of a week or so. I think swordtails are the same way. Mollies might be like that also. She will have some more if she is still really fat. Congratulations on the baby fish!
