So is there no point in buying ore quarantined fish? Where do you buy your fish from?I'm in the "no quarantine" camp as I personally found that, well - it's only effective if you're 100% diligent - which almost never happens. I'm coming up on just over a year and a half of not quarantining any of my fish (July 2021). I try to select the healthiest and most active fish from my LFS, provide a freshwater dip for flukes and acclimate them properly.
I've gone from roughly 16 fish post-velvet (where quarantine didn't work) to a current stock of 50 today. All healthy and disease free. I haven't had a chance to read through the entire 142 pages (working on it!), but I do run a UV to keep things in-check along with an ozone system. And I don't do water changes.
