I saw one of my Corys flash too. I came here to get some advice on the best way to treat them.
In my tank I have juvenile Dojo Loaches, Corydora, Kuhli Loaches and Danios.
I also have plants and Green Algea.
All I know for now is that I am starting to raise the temp till I get some advice here. I have Formalin, Rid Ich, Quick Cure and salt on hand. But I have been told that loaches cannot handle Malachite Green which is in the Rid Ich and Quick Cure and I just read that Formalin is very toxic to them too, and that they cannot tolerate high salt levels! I don't know what to do.
The good news is it's a bare bottom tank. So that willl make it a little easier to rid the Ich.
Please help.
