The situation is now worse. It seems that a couple of fish from my main display are also showing symptoms. My anthia has poo symptoms now. I am guessing from the first firefish before I was able to remove him to qt. She is also swimming around frantically trying to eat bubbles that appear. This is crazy. I don’t even know how I would be able to catch them all to treat them. I don’t even know what to treat them with. They were all on a diet of Metroplex and Focus for 10days after the first incident.
