There are plenty of ways to put fish down. They actually sell something called "fin-quel". It slowly puts the fish to sleep. That's the most humane way to do it... I've also heard of people putting them in the freezer till they slowly get so cold they shut down. And some people do it the old fashion way use aspirin..
thank you! and you're lucky to have so many :3 My other betta got this infection of sorts, that I've no idea how he got. It just looked like his fins were rotting away, and he turned brown instead of blue. I put him in a separate, tiny tank with water from his original tank, but he looked like he was in a lot of pain, so I eventually decided on letting him go (I put him in a cup of boiling water, for a quick and painless death). The people at the pet store said it was actually a bit normal for bettas to get that kind of infection, and that it wasn't contagious (luckily). It was apparently just a betta-thing Other fish can of course get it too, but bettas are more prone to getting it.
I knoooow, I love my boys! They're all such characters, they're my fave fishies :3 Awhh, maybe fin rot? Basically it's where the water conditions aren't perfect so their fins rot down. My boys with longer fins get it sometimes, you can usually cure it by doing 25% water changes with warm, dechlorinated every day for a week or so and it should get better. Also, a good way to euthanize them is to get some clove oil. It's usually used for tooth ache but if you get a jar of their tank water water and add 15 drops of clove oil, then add the fish, they'll go to sleep and then die. I've had to use it with ill fish before and it's nice to know that you're doing the right thing and they won't be in pain.

I'm usually not one to like fish, but this fish is Beautiful xD this shot is wonderful, probably one of the best i've ever seen of a fish, usually a tank or something would make it fuzzy. Its almost as if you're in the water with the fish here :'D
That's plenty creative! We had a goldfish named "Goldie". And we have another fish called "Fishy". And to replace Goldie after s/he died I got a red and black one and named it Hernando the Christmas Fish 'cause I got him for Christmas o3o
