I have a 40 gallon tank with an electric yellow lab, albino bushynose pleco, albino clawed frog, and a rtbs, all are pretty small (around 2"). I suspected the tank might be infected with ich as I observed the fish rubbing themselves on hard surfaces every once in a while so I treated the tank for ich, I then noticed my rtbs being much less active and swimming a lot slower. I read today that they are sensitive to ich treatment so I figure that is why, so now that I know I will definitely not use the treatment at full strength. Any opinions or past experiences with this or similar situations would be helpful.
