sorry to that you have swimming bladder problem. i totally agree
with the rest, let the nature take its toll. however, i would like
to share this one instance i had with gold fish having same concern.
i put it in hospital tank, with enough water to swim, not too deep
nor too shallow. put some methylene blue, pure salt to enhance oxygenation,
and soaked whatever food it takes to garlic oil before feeding. it was able
to recover and live for another three years with me until i sold them to
new owner.
hope this one will works for your jade eye cichlid.
