Feeding fish with Zoe soaked food will also speed healing. I had a saltwater mollie that lost her tail fin due to a rock falling on it. I put her in a hospital tank with lights out most of the time, keep clean water with top notch quality, tried to keep my hands out as much as possible, used stress coat and Zoe. You'll notice infection, it will be swollen red streaked. If that happens maracyn or erithromicin will need to be used. Hopefully she learned her lesson and won't try this again. Best of luck.
