She's is not getting any better even her fins look a bit swallon its not fair to keep her alive, I have read on internet to put her in a bag of ice, is that a nice way
Put her in a fish bag with the end sealed shut tightly and hit her on the head with a hammer. Enough to disconnect the head from the body if possible as otherwise it may just stun her and leave her in pain till she dies slowly.
OK. Just make sure the fish is dead before getting rid as sometimes doing the Clove oil doesn't kill them, it just puts them to sleep and then they wake up whilst out in the bin or something.
