I was doing a water change on my QT and afterward there was a dark spot on my ringtail tang. There was no spot on the other side so I started to worry. Two thinks happened that might have caused this.
#1 while doing the water change part of the tank lid (a 6" X 12" 3/8 inch thick piece of plexiglass) fell into the tank near where the fish hides
#2 After the water change (heater was unplugged during water change) I could not find the fish and when I did he was shoved vertically between the heater and the sponge filter. I thought he was dead for a minute.
So like I said the spot was dark and about the size of an almond. An hour or two later and the skin has flaked off there and now looks like normal fish color. Should I be concerned? Does this look like it could be something completely different? DO I need to treat the fish?
Thanks in advance.
