Pls help.
i used to be on here more and i have entirely new tank its 20 gal with 3 female bettas one of which looks like she got ich on top of her head (picture below). Theres also snails and shrimp and a few corries. I know copper based ich medicines can kill like half of my tank so i did a 50% water change and turned off the lights and turned the temp to 81 and put salt water in it. I saw her and did this all this morning is there anything i can do to help her more or speed up the process and protect the rest of my tank at the same time.
