Oh my I wasn't expecting that!
Diseases:
- Diseases in livebearers are very easy to spot since they are such active fish.
- Most common diseases include:
Swim bladder disorder
Ammonia poisoning
Intestinal worms
Ammonia burn
Birth defects
Livebearers tend to interbreed if they get the chance. This can cause severe birth defects that will lessen the fry's chances of survival.
Looking at your baby here, I think they might be struggling with swim bladder development. I don't know much about the mortality rate on this one but I would always prepare for the worst situation possible.

I was thinking something along those lines, i thibk some neurological issue. Something similar happens in hamsters if they are inbred, theyll start just doing flips back words . Im thinking this is the fish version. Unfortunately the molly i got was already pregnant so im not sure if she did mate with a relative or not she her self is s Dalmatian so maybe the hybrid mix is overwhelming enough
I've seen this plenty of times with adolescent Molly and some Platy I've bought from pet shops.
They do the passing out twister thing you filmed, WW2 movie fighter jet death roll to the ground and twitch then rocket speed swim with passing out in the middle of it.
Afterwards they look like nothing happened and act normally.
But eventually, once they just don't wake up after passing out.
I believe it's some genetic neurological disorder from inbreeding or some parasite/pathogen that attacks their brain/nervous system.
I've been unable to cure it with of the shelf parasite/bacteria/fungal medication.
Thus far: I lost all the fish, with that strange behavior, prior to reaching adulthood.
It's either poor water quality, or an infection in the brain, or a genetic defect.
The common cause is poor water quality that allows protozoa to build up in numbers and infect the brain.

Wipe the inside of the glass down with a clean fish sponge.
Do a 75% water change and gravel clean the substrate every day for a week. The water changes and gravel cleaning will reduce the number of disease organisms in the water and provide a cleaner environment for the fish to recover in.
Make sure any new water is free of chlorine/ chloramine before it is added to the tank.
Clean the filter if it hasn't been done in the last 2 weeks. However, if the filter is less than 6 weeks old, do not clean it. Wash the filter materials/ media in a bucket of tank water and re-use them. Tip the bucket of dirty water on the garden/ lawn. Cleaning the filter means less gunk and cleaner water with fewer pathogens.
Increase surface turbulence/ aeration when using salt or medications because they reduce the dissolved oxygen in the water.
Add some salt, (see directions below).
--------------------
SALT
You can add rock salt (often sold as aquarium salt) or swimming pool salt to the aquarium at the dose rate of 2 heaped tablespoon per 20 litres of water.
Keep the salt level like this for at least 2 weeks but no longer than 4 weeks otherwise kidney damage can occur. Kidney damage is more likely to occur in fish from soft water (tetras, Corydoras, angelfish, Bettas & gouramis, loaches) that are exposed to high levels of salt for an extended period of time, and is not an issue with livebearers, rainbowfish or other salt tolerant species.
The salt will not affect the beneficial filter bacteria, fish, plants, shrimp or snails.
After you use salt and the fish have recovered, you do a 10% water change each day for a week using only fresh water that has been dechlorinated. Then do a 20% water change each day for a week. Then you can do bigger water changes after that. This dilutes the salt out of the tank slowly so it doesn't harm the fish.
When you do water changes while using salt, you need to treat the new water with salt before adding it to the tank. This will keep the salt level stable in the tank and minimise stress on the fish.

it's probably it’s swim bladder commonly known as a known as a belly slider, a newborn fish must rise to the surface to fill their swim bladder sadly your Molly didn't make it if it hasn't correct itself within 48 hours it won't recover , water conditions can cause similar problems and it's very unlikely to be genetic.
Fish with swim bladder problem don't swim normally and pass out on and off?

you will never find the true problem, fish in that condition or similar conditions should be discarded

I would be careful with any fry that you get from now on.
What Colin gave you is very good information. Definitely follow that. I am going to lean towards a genetic defect but keeping your water quality in tip top shape is important for fry survival.

Update; the fish is back to normal as if nothing happened and stopped this odd behaviour. I think he just wanted attention.
Good to hear. Hopefully, you're right...
If it doesn't happen again then that is great. However, monitor the fish, it might be having random seizures.
