Running a tank fallow

Great feed back, thanks
I thought I was doing everything right before my fish went into my 150 dt... treated all new comers with cupramine and quarantine in a 50g for about 5 weeks. I got 3 new little guys and just observed for 6-7 weeks without cupramine. Ate lots in that time with no outbreaks. Decided to try something different because one was a flame angel and I heard doesn't do well with copper.
Put them in the dt and with in a week things go haywire. I think its velvet. My
Majestic angel looked like he was dusted with flour and his fins started to deteriorate fast, he was gone in 2 days. He died while in quarantine and cupermine ramping up to proper levels at the time....he went fast. I waited to long before I cleared out my display tank and started to treat. Now its a waiting game. Nice thing is my quarantine is well established with lots of filtration and
Filter media for bio load. Hopefully there isn't much more fish loss. Try the fallow thing for 3 months and see what happens.

Velvet is 6 weeks.

I do not like to treat anything with copper (poison) unless I absolutely have to.

I have found that if you quarantine a fish in a separate tank with a biological filter (low stress) you can watch closely for anything to happen. 9 times out of 10 nothing does. I always do this before I put a fish into my main display.

Some have had success with no quarantine but I have lost a lot of fish over the past 30 years and 2 times completely lost every fish in my tank.
