I was doing a water change, with my usual airline hose. It's for my guppy fry tank, acting as a miniature gravel vacuum. I looked away for a sec and there was a guppy with her head stuck inside. I didn't expect this as they usually keep well away. I quickly squeezed the hose to let her out but her gills and head are bleeding. What should I do??? I quarantined her in a bucket. I don't expect her to survive, but how can I help stop her suffering?
