My fish got stuck in filter, tail injured and not moving. How to help?

Updated On September 23rd, 2025

Pet's info: Fish | Unknown - Fish | Female

My fish has got stuck in the filter, I have released her from the filter but she is breathing heavily and has damaged her tail. She’s gone to the bottom of the tank, is not moving or eating. I have put her in a separate tank so the other fish do not bother her. Her tail is red and looks like it’s filled with blood. What can I do to help her?

Keep her in the hospital tank until she heals. maintain adequate water quality and temperature via frequent water changes, filtration and the use of a small, submersible heater. Plain aquarium salt (NOT table or Epsom salt) can be used as a general tonic to reduce stress, increase gill function, treat minor infection and aid in recovery. Dissolve up to 1 teaspoon of salt per gallon of water. Treat for 10-14 days then reassess fin condition.
