You can get by with pairs, but you definitely shouldn't have another GT, especially male, living in the tank, too.
To the OP, if you put the fish down, the best way I've found is a method I first read about on here, which is to wrap the fish in some paper towels and place it in the freezer. The cold will put the fish down quickly and it's relatively painless compared to other options.
(Sorry, missed your last post. Sorry about the outcome. I need to do a better job of paying attention to OP dates on these threads.)
