My fishes tank seems to have some sort of film over the top of the tank. There is also a cob web like substance coating everything in her tank. I have tried many things to clean it up, but none have worked. It didnt seem to affect my fish. A few days ago I came home and saw her laying on the bottom of the tank. She was very lethargic and has fin rot starting. :(

Symptoms and Treatment

When did you start noticing the symptoms? The tank has been weird for months. I tried so many things to make it right, but nothing worked. She appeared to be unaffected buy the cob web like substance and film over the water, but 5 days ago she just stopped swimming. She seems like swimming is harder too.

How old is your fish (approximately)? Ive had her for about 2.5 years. She wasnt full grown when I bought her.
I got a chopstick and swirled it around in the tank trying to get all the coating off. I turned on my filter, which is decently strong for the tank size. The film and cobwebs seem to be gone, but they will return to settle on things if the water is left stagnant. Not sure what is the problem and how to fix it.
Thanks for any help offered.
