So, I have the dreaded Brooklynella. I read on this forum that it is a quick acting parasite, and boy is it. I noticed the symptoms on my purple tang yesterday morning. By this morning, I lost my 3 O. Clowns, coral beauty and the culprit blue eye kole tang. There are 3 remaining fish... six line wrasse, purple tang and yellow tang. The purple tang is infected and not looking good at all. I am working on QT tank to hopefully catch, QT and treat the 3 remaining fish. Fingers crossed!!!! That being said, I am going to go fallow for the recommended 6 weeks (might even go longer as I'm a bit skittish now!). My question is, do I need to medicate the tank once it is fallow for the 6 week timeline, or just let nature run its course during that time. I do have corals, rock, rose BTA and some crabs / snails in the tank that hopefully I don't have to remove during the fallow period.
