I just wanted to say that disposing of fish should be very thoughtful. You can bury them and give them a 'funeral' especially for the ones who have really meant something to you.
Wrapping a small amount of paper toweling and placing them in the garbage is best as you are not adding non indiginous fish into the sea/wherever your city pumps human waste.
But UNDER NO CIRCUMSTANCES flush them!!!! It is illegal where I live. If you care any at all for the environment PLEASE don't use the toilet as a place to dump fish.
BTW Chaz, I'm sorry its come to this. I am glad you are brave enough to use euthanasia as a method to stop your friend from suffering. I haven't been so brave, but my hubby has and I'm grateful he's been able to do that for me when I've not been able to. RIP. Oh, and a way of remembering is to put him into the rainbow bridge on this forum if it still exists and its still operating. Its kind of a memorial!
