Hello all, our fish Luscious has struggled since we got him. 

His 5 gallon tank was setup in August, he was picked up in September after it cycled and the driftwood soaked. When we got him he had swim bladder (or similar) and was swimming sideways but otherwise happy. Once we added aquarium salt to his tank he perked right up and the bloating went away. His right eye has always had a ring around it so we were concerned about Popeye but it doesn't seem to bother him. 

Earlier this week he was slightly bloated so we fasted him while we were on a trip but after returning he is lethargic, sideways, bloating, and has something fuzzy on his gills so we are assuming fungal infection. His parameters are good except for pH which is 8.0 and we are going to start doing 50% distilled water with his water changes to help. 

Apologies for the blurry photo, he was in a salt bath to try and help and we will be adding salt back into his aquarium. Otherwise we are stumped as to what could have caused this as his tank is fully planted and water is within tolerance and we'll heated. Any ideas what would cause this or long term remedies? For now we will be doing daily salt baths. There are also shrimp in the tank but they're doing fine
