i have a female platy who for a while has kind of been hanging down on the bottom but she has always come up to eat and i’ve seen her swim around just turn so i just assumed she would rest. now she cannot get off the bottom. she won’t eat she won’t swim. she just lays on the bottom. she’s super lethargic too. she’s been gasping for air and stuff. should i just euthanize her? what method is the best way? i was thinking clove oil.
