On saturday morning I noticed that my flame angel had some white spots about sugar sized on him. Then I noticed that my royal gramma had the same thing later that day. I went to the lfs and got some medicine for ich, this is what they recommended. Treated the tank when I got home. Woke up sunday morning and both fish were dead. What could this be? Does ich kill that fast? Just trying to figure out what happened. Had flame angel for 1 month and royal gramma for about 3-4 months.
