What is your deciding factor to euthanize? In other words, after what point do you feel there is no coming back?

I recently lost two fish i bought from the fish store, very nice looking GT fry. I quarantined and treated them with Metro for a week before introducing them to a community fry tank. Everything was fine for another few days, but then noticed one not eating, gulping for air so i removed and within hours was dead. Two days later the other fish was same situation and I decided to put it down.

Now at least a week later one of my personal fry is having trouble, but all others seem fine. Lethargic, washed out, not interested in food, didnt fight me netting it at all. My gut is telling me its over, but wondering if there are tell-tale signs that a fish has reached a point of no return.....
I feel one week is way to short of a time to qt before introducing new specimens to the main tank

you're right, but man they looked great, were eating good, had been on antibiotics for a week, did well after the fact for a few days, but just didn't wait long enough.

Im no expert, we all make mistakes.

how bout you share a time when you made a mistake that ended up with a loss?

Lol, how much time do you have. I never used to quarantine so please don't take my comments the wrong way
Water changes, you mean top off right?
150 can hold a silver arro cant it
They ought to get along so...
Etc.
 
I never use any med unless I know the disease, and I'm sure it is effective against that particular disease..
1 week is not quarantine to me, and it looks like you may have deduced this as well, for your recent deaths.
My normal quarantine is 2-4 months, 2 months with an absolutely perfect appearance, anything suspicious at all, 4 months.
A suspicious clue might be a sore, an attempt to scratch, or simply being listless.
Many diseases can take months to show symptoms.
A friend who runs an aquatic exhibit at a zoo, quarantines minimum 6 months.
For me a bacterial symptom like a white sore, or listlessness for something such as columnaris will cause me to euthanize. Something simply treated like ick, or a disease that requires no meds at all like lymphocystis, or a non-lethal wound, I would attempt to save.
The colomnarus bacteria and others like it can survive dormant in dried mud on tank glass for months, and easily reinfect the system when water is added. so I would euthanize the fish, and bleach anything it came into contact with (tank, nets, tubes, everything).

So after 2 months if nothing seems odd, fish eat normally, full of spunk if you will, you would say they most likely have a clean bill of health? At that point you would feel comfortable adding them to an existing tank?

Thanks for sharing your knowledge
 
Yes 2 months, I don't find that amount of time excessive wait before I put them with other important fish, or put the quarantine tank back in the line with other fish, and main sumps.
