Hi guys,
Long story short - everyone in the tank almost died (death related poisoning, then ick, then quarantine, then stress = 1/3 death

)
Anyhow the
clown fish did survive but now he's sitting on the bottom!! He's been there for over 2 weeks! He swims in a small radius, ALWAYS on the bottom and has cleared the sand from where he sits. Sometimes he sits a little on his side, but not upside down or anything. He eats but doesn't venture out of his 4 inch pothole. What happened? Can a fish lose their swim bladder or why doesn't he surface or swim?
