I found my big female guppy on the carpet and was very stiff but once I soaked her in water she revived. I put her in the tank and she ate a bit, but this morning she's acting sick and not eating, her skin and part of of tail are scratched up pretty bad. She swimming but my cherry shrimps keep riding her and trying to eat the bruised skin. Is this harmful for the fish or will it help it heal faster? thanks
