This is kinda weird, but I have a female guppy and she seems to have had a stroke. She is swimming on one half of her body and the other half is still. She has been like this for three whole days and will not die...I feel bad because I know she is suffering. How should I put her out of her misery (without flushing her down the toilet alive...) Or should I just let her die on her own? I've had guppies for many years and none of them ever got like this, I just usually found them dead overnight from old age or whatnot. Thanks!
