Leaving the hospital tank on the floor is fine if that is less stressful for your sick dish. Be sure the top is secured to prevent her from jumping out or other pets from getting in. Survey the area around it for any negative stimuli, such as loud noise, cool drafts or strong vibrations. Make sure the water is sufficiently heated as well. Treat with a combination of a broad spectrum antibiotic and plain aquarium salt (NOT table or Epsom salt). You can find an antibiotic in the aquarium section of the local Petco. Follow label directions carefully and remove the carbon filter insert during treatment if indicated. Dissolve 1 tablespoon of salt per 5 gallons of water in a cup or two of tank water and gently pour it into the tank. Treat for 10-14 days then reassess Leela's condition. Be sure to maintain pristine water quality and keep her as stress free as possible. If you don't want to medicate, you can try a combination of Pimafix, Melafix and StressCoat or similar conditioner. Follow label directions carefully and maintain clean water and a stress free environment.
