Will apologize right from the start. I have limited info. This photo is from a coworkers tank. I have very little experience with tropicals. Here is what I know. 55 gallon tank. Added a Betta shortly after set up without cycling tank. Betta is still alive. Added two platties few weeks later one of which died other is still alive pictured here. Tank set up about 1.5 months now. I am concerned about the white spot on fin and the fact it is torn up. And the long white poop is obviously a concern. She does not have a test kit.so don’t know water parameters. I know missing info but can anyone help.

It's nice of you helping your friend. I suggest having her take a sample of the aquarium water to a lfs they will test all parameters for free or small fee. The Platy looks like it has fin rot but not entirely sure.
 
Lol. She is actually on her way to do that. She ordered a test kit the other day. Should be here Monday or Tuesday.

The spot could be lymphocystis. Should clear. Would make sure the water is clean. Poop can be influenced by what it’s eating. So would post the water parameters and diet. Is it acting normal?

Generally fish that have been subjected to a cycle, raised ammonia levels, etc..die within a few months to a year of exposure even though they may survive the initial exposure the the toxins. This fish looks in really bad health, possibly due to the bad water quality it has had to encounter. Platies aren't so tough anymore. They're very inbred and its easy to upset their well being. I'd advise a more frequent water change schedule for a while and monitor the poop. Any abnormal poop may indicate parasites/worms, which is unfortunately also common for livebearers now. The platy also seems to have bacterial infections going on,probably due to initial ammonia burns but this is again due to poor water quality and can clear up with more frequent water changes, providing the tank isn't cycling still.
