Gourami Sinking, Can't Move

[robbie1299]

My baby blue gourami has been sitting at the bottom of the tank for about 2 weeks now, either on his side or upside down. Has to swim is circles (upside down) to move to get food. Looks miserable.

• Water chemistry is perfect
• 80 degrees
• Have had him for about 6 months - history of floating on his side, but never sinking like this - one time it was a fungal infection, successfully treated with bay tree extract
• 16 gallon tank with 2 upside-down catfish, 2 bamboo shrimp and a 3-inch albino loach
• tried feeding him mashed frozen peas once a day for 2 days - no effect
• Currently in 6th day of bay tree extract treatment - no obvious effect
• Lowered water level slightly to increase distance that water has to drop from filter so as to increase water oxygenation - just did this about 4 days ago, so I know it's not the cause, but it's not helping, either.

What do I do?

Try withholding all food for 3 or 4 days.
