My African dwarf frog is dying, bloated, sores. Protect other fish?

Updated On September 23rd, 2025

Pet's info: Amphibian | Unknown - Amphibian | Male | unneutered

Hello I had an African dwarf frog die 2 days ago and another one is dying right now. My water is normal except my nitrates got up to about 40 so I did a 50% water change and they are at10-20 now. This frog seems to have sores and be bloated. What can I do to protect the rest of my fish? I took the frog out because he is dying right now and can’t swim and my betta wanted to eat him.

Maintain pristine water quality in the main tank and monitor the fish for similar symptoms. A bit of aquarium salt ( not table or Epsom salt) can be used as a general tonic to reduce stress, improve gill function, treat minor infection and aid in recovery. Dissolve 1 teaspoon of salt per gallon of water in a cup or two of tank water and gently pour it into the tank. Treat for no more than two weeks then perform partial water changes to decrease salinity. Use only conditioned water that is temperature matched to prevent stress or shock. I am sorry for the loss of your frog. Your remaining ADF sounds quite ill by your description. Again, maintain pristine water quality in the quarantine tank with a water temp of 78 F. ADFs, and amphibians in general, ate quite sensitive to changes in water chemistry. Elevated ammonia or nitrite levels can kill. Other possibilities for the bloating include improper diet, obstruction or kidney failure. You can try a fast for a couple days along with salt baths. This may relieve the bloating. If it is dropsy, unfortunately by the time a frog is bloated, the survival rate is very low.
