I have a 10gal tank and I put recently purchased a betta from petsmart with some pretty decent finrot. The fish is active and eating but he needs some help growing his fins. I figured some aquarium salt may help (2 TBS for 10gal).
Here's the problem - i have two ottos in there. I have read they are not tolerant of aquarium salt. It gets too cold in my apartment to have a hospital tank for the betta (I don't have the room for another tank which I can put in a heater).. Any ideas? Has anyone used aq salt with ottos and been OK?
