I don't buy that shit. I've had fish with swim bladder problems live for better then a year.
I've had deformed fish live a long, and healthy life, upside down.
I NEVER put a fish down. They may recover, they may not. Let nature run it's course. I deal with kids on a daily basis that some are very close to what you are talking about. We don't put them down, and, they smile, laugh, even if they can't move their arms and legs, and barely their hands. Is it sad? Yes, but respect the will of the Lord, and let them live thier lives out.
I've had bad luck with quarintine tanks, since you are taking a fish out of a comfortable environment, and putting it in a new one, and change is stress.
Unless I'm REALLY sure what they have is communicable, I let them stay in the original tank. Tetras are really tough fish, as a general rule.
I would have given them a chance to recover, or, die.
I recently had a child nearly cut his finger off in our door. He had no pain.
Simply put, he senses pain, and tastes, differently then I do. What you precieve as pain and misery, may very well not be the case.
Remember, my cat, who has a way better sense of smell then I do, eats live insects, and loves to lick her ass.
:wink:
Now why do people put their perceptions onto fish, etc?
I have had one cory cat, named upside down grumpster, who lived over a year, in a small tank, on his side, or upside down, much of the time.
He couldn't compete with the other fish in the big tank, but, in our 20 gallon breeding tank, he was happy as a clam, eating, and living, with all the baby fish I hatch, and grow. He died, but, that's a years life not deprived.
He also did not infect anyone else.
