What are your water parameters? Did you completely cycle the tank before adding the fish?

[Gaurav]

No Unfortunately I didn't...this was a gift and is my first fish tank...I was counting on the dealer ...he didn't mention or provided any dos and don'ts ...I am being stupid went by his words and didn't do enough research..now I am feeling terrible..

Initially I had top filter but I believe it was stressing her more out ...she would fade ....today I installed Eheim 250 cannister filter....and also a sponge filter connected to aerater ...since installation he has become way more vibrant as compared to past days....that's him in initial days

I'm not sure what could be on the glass. But aquarium salt should cure the popeye. I would do 2tsp a gallon. I'm assuming that because its a flowerhorn you don't have any other fish in the tank, right? What are your water parameters?

Salt has helped me when I dealed with pop at the ratio of 2tsp a gallon it wasn't till about a week until it was gone. Your going to want to make sure the tank is clean (every other day waterchange) and put salt in every day (2tsp a gallon)

Make sure you get aquarium salt or epsom salt, not marine salt.

You can use maracyn with the salt for bacterial infection

If you're new to all this, It can be overwhelming.   
First off, your tank probably isn't cycled properly and toxic stuff is building in the water,  Ammonia and Nitrites.  Getting a test kit that can test for these will help you diagnose any issues, they sell master kits that have all the basic tests needed. 
The best thing to do would be change water frequently,  like daily or every other day till you can see there are no ammonia or nitrites showing on the test, or at least a month if you can't get a test kit.   If you have public water, you most likely have chlorine or chloromine in your tap water,  you can add water conditioners to neutralize that immediately, or let the water sit out for a few hours before adding it to the tank.
 

You can add salt to the tank as that should help with everything.   I would just keep the water clean, stay up on water changes until your are sure the tank is cycled.   And keep the tank heated.  If you do add salt, make sure you add salt to the water you change too.
