How long have you had him/her?

There is no way to check what he/she died of, without a test kit. Please get a test kit in order to find out what happened. No matter if fish are dying or not, you need a test kit. I recommend this one:

Hope I helped!

In what size tank was he in.

 

[Mckitrick]

20 gal

 

[calfishguy]

Hard to tell. Once you get a test kit It might be easier to know.

Well i did a water change so what ever was the problem is gone now

What's your water change schedule?

 

[Mckitrick]

About 20% a week

About 20% a week

You probably needed to do better water changes. 50% a week is a great way to keep a tank clean. (If you think THAT'S overboard, I must tell you I do the bucket method to empty out 25 gallons of water WEEKLY from my 55 gallon tank.) But without any type of test kit, there's no telling what happened to your Molly.

25% a week is fine as long as the tank isn't overstocked...

You could always get a python to speed water changes up.
