Treatment for popeye, lethargy

[FishyWishy]

Hi all,

Our boy has been lethargic, is biting his tail terribly again, has a small bump on his belly (both sides under his top fin) and now has developed a popeye. :(( What does this mean? How should we treat this? We want to get him some help as quickly as possible. :((

Many thanks

Sorry your Betta is not well...we need some more information....

How big is the tank, how much and how often are the water changes, water temp, filter, live plants, additives used, tank mates, appetite, how long have you had him and what kind of treatments has he had in the past 2 weeks if any, is this both eye or just one...can you post a pic.....
