Last week I found out what ich was because I lost 4 cherry barbs to it. My rainbow shark has managed to hold on though. I started a treatment and started to see improvments so I reduced my treatment to once a day instead of twice. the very next day my 2 remaining cherry barbs have the white dots on all fins and one is obviously stressed and probably wont make it through the day. I have quarintined it to the best of my ability. This specific barbs jaw also seems to be stuck open and I'm not sure why. My rainbow sharks color has also started to fade. Does anyone know what I should do next? This has become pretty frustrating since this is my first tank.
