Hello, relatively new saltwater keeper here. I’ve always known that quarantining is the way to go BUT I never did it despite hearing of all the horror stories of tanks getting wiped. I thought I would last at least a couple of years before getting an issue but nope. 2 months in, half of the tank wiped due to velvet and possibly brook. Ich was also present in the tank but did not show up for the end game. I’ve spent so much time now trying to treat the survivors. Researching, seeking for meds, destroying my scape to catch fish (now imagine if I had corals), dipping the fish, digging through my house to set up the emergency QT, ammonia spikes, losing my salifert copper color sheet etc etc. Now I have to leave my display empty for 2 months with nothing but a cleaner shrimp in it. I’ve learned my lesson, 2 months in. Those who never had a problem, you are lucky so far. Just wanted to share my newbie experience, 2 months in.
