my fantail has had air bladder problems for about a year now. we have tried my things from putting her in a hospital tank with low water so she stays upright, treatments of different types. she recently just got over finrot, which has resurfaced even worse. she cant eat anymore because she just cant stay upright, she often crashes for 30min. or more. we have decided, since we have given her over a year to recoup somewhat and she's not, that we will euthanize her. i had read there is a mixture of i believe vodka(?) and something else that will kill the nerves, thus making it a painless passing. anyone heard of this? i really dont want to freeze her, imagine if someone froze you? i dont believe this is a humane to euthanize, sounds painful to me. any help would be great. thanks!
