Balloon Belly Molly Lying On Bottom Of Tank

I have a tank of mollies that has been running fairly stable for about 2-3 months, now. There are two male regular mollies, and one female balloon belly molly.
When I first started my tank, I was experimenting with trying to breed mollies. I got a few balloon belly mollies, but two of them died, and I have just the one left, plus the two males.
A couple weeks after having the tank, the balloon belly molly have birth to about 5-7 fry. I put them in a fry net, and all was fine for about a day.
The male mollies had never been aggressive before, but after the female molly gave birth, they had been kind of, in a sense, bullying the female molly. They nudge her around, nip at her rear end, and chase her around the tank. I figured the problem would probably stopped, but it never did.
Since then, the female molly has given birth two more times, and there were fifteen fry in the tank. I most of them in the fry net because I didn't want the others to eat them, but I left two out on the tank as kind of a test. The other mollies never attacked them, and they were in perfect health.
However, two days ago, about a week after giving birth for the third time, the female molly started lying on the ground and not moving. She is breathing, although she looks like she's breathing heavily, and she shifts sometimes, but she just lays on her side gasping and barely swims around for food. I released the fry into the tank, and she swam around a bit on the bottom with her babies, then went right back to laying on her side.
None of the mollies bother the babies. Even the most aggressive molly in the tank doesn't fight them for food. But I am so worried about the female molly.
I have an isolation tank, but it hasn't been cleaned since one of the fish from our other tank had ich, so it definitely needs a good cleaning and a water change. I don't have any conditioner or purified water, at the moment, so there isn't much I can do until I can go to the store.
Please help me figure out what I can do! I'd love to help save my molly.

Can you give us more information?

Tank size?

Water parameters? pH, temp, ammonia, nitrites, nitrates

How often do you do water changes, and how much do you change?

Males can harass a female to death. The number of females should double the amount of males. Do you have a plan for the fry? It may be best to rehome the female, rather than add more, so you're not overrun with fry.

Tank size is a ten gallon tank. Water parameters are perfectly safe, and I usually do water changes when the water level starts getting a little low.
Could I move the males to our other tank? We have a couple of other mollies and an angel fish. I could add more females to this tank. Thank you for the information.

Can you list specific parameters please?

And how often are those water changes then, and how much do you change?

It sounds like a water quality issue. Tank is overstocked (29 gal minimum for mollies due to their size and biolaod) and it doesn't seem that you do enough water changes if you're waiting until water evaporates.

What size is the other tank with mollies and the angel? How many mollies are in that tank?

I am not home to give the specific water parameters, but the test strips I have are also on the cheaper side and only show whether it's safe, stressful, or dangerous. I will try to do water changes more often.
In the other tank, there are two mollies and the angel fish. The tank is 29 gallons, and we were planning on getting a small suckerfish or two to help clean up a bit of algae on the heater, as well as some other fish, but we're not sure what kind of fish.
Thank you so much for the help!

You are the best at preventing and controlling algae. I would not get a fish to take care of this for you.

In a 29 gal with an angel and mollies, I don't think you have room for much else. Adult angels can get very large.

I would rehome some of your mollies though. A 10 gal is too small for even one molly, and your 29 gal isn't big enough for so many mollies with the angel.

Or can you upgrade your tanks?

I'll try to get bigger tanks when I can, and I'll do some research on how to take care of the algae problems thanks!
