Hey everybody, recently I got a trio of African clawed frogs in a 29 gallon aquarium. Their tank is pretty bare bones and there is a sponge filter BUT it isn't cycled however I do 75% water changes every other day, so the water quality isn't terrible but it also isn't pristine. I noticed one of the frogs is kinda puffy and I was thinking is it bloat? There is only about 15 to 18 gallons of water in the tank, should I put in 3 tablespoons of espom salt? Thanks
