Hi and welcome

sorry to hear that your fish is not well

Your platty is probably suffering from the ammonia in your tank, you really need to read tis guide http://www.fishlore.com/NitrogenCycle.htm and start the process by doing a 25-50% water change to the tank and add prime or stresscoat+ to the water as well as your normal water conditioner.

What are you using to test your water by the way? If you are using test strip they are not very accurate and you would be better servered with teh API master test kit that most folks here use as they are far more accurate.

My Ammonia is slightly high. Its 0.75. Also i do 2 25% water changes weekly and one 50% water change monthly. Last, I use the API master kit.

Weird that after a month your tank is not cycled... have you changed the filter media recently?

With the ammonia that high you want to do at least 25-50% water changes daily.

Mr.Guppyman

Well Thanks for the help!
