How many times should i do a water change?

My question is that how many times should i do a water change if i want to keep my black molly fry healthy and keep their growth rate steady.

Right now i am trying to make my black molly pregnant and i want to know that what will be the suggested amount of water change for that and what will be the suggested water change amount once i get a few fry? I have a 15 Gallon tank.

If you keep the fry in their own tank you can do water changes daily or every other day for optimal growth. Weekly would probably be acceptable if you don't overfeed them. Depending how many fry survive. If you plan to keep them in the same tank as the parents, I'd continue your regular water change schedule, maybe a bit more often.

If they are in their own 15 gallon tank, that sounds about fine to me. Make sure to try to avoid over feeding them, though. And space out the 6 feedings. Once every 2-3 hours I suppose. Freshly hatched baby brine shrimp will be the best food for fast growth. I recommend a 50% water change every other day. Also, I do recommend keeping a filter in the fish tank. If not they might need even more water changes. Make sure to keep the tank at a temperature around 80. If the temperature is on the low side of around 72, then they will grow slower as their metabolism is slowed down.

I'm no expert at this but I've researched it a lot. I have a 10 gallon fry tank. I feed them 3-4 times a day and change the water every other day 50%.

How are they not available? Order them if not. You should hatch your own- it's very easy! :)

I'd feed 3 times a day that's enough.
For the fry and good water quality rather then once a week 40% w/c I'd do 2xweek 20% w/c.
