Question on Ich/Fish Diseases From non-fish additions
 

I was thinking about Ich today and a lot of the stuff I read stated rock/corals can bring ich into the tank if a cyst is attached somehow. Does this mean that any non-fish addition could lead to Ich in the main display tank if the new addition is not quarantined to minimum of 72 days (disease fallow period needed)? This is the only way I could see a tank being completely free of Ich.

If this is so, how do you quarantine a coral for 72 days without lighting and proper water movement? You would basically need a full secondary tank setup, be it smaller perhaps, that has the same lighting/water movement. That gets spendy.

Thanks,

Yes, 72 days in a fishless system for rocks, snails, corals, etc.

For corals, I do have a secondary setup (a 20g long) with an AI Prime and MP10, which doubles as a frag tank.

It's all about level of risk you are willing to take. With snails, I usually put them in a 5 or 10 g qt tank for a week or so before going into the DT. For corals, I usually cut off the frag plug, dip, then put it into the coral QT for a month or so.

When a coral comes in for you, how long do you quarantine? It seems to me if you don’t quarantine non-fish for 72 days, you still have the chance of acquiring Ich.

I can't be bothered. That's way to overboard in my opinion. Chances are small.

Sometimes my mind goes off on its own and that’s where I end up. Lol

I see fish in coral tanks at LFS all the time, And then when I see one scratching/rubbing, I don't buy any or if I do (cheap ones) it goes in a coral QT for the duration. Most live some have not.

Here's a chart for ya

Ich cysts won't attach to slugs and cucumbers, the free swimming stage can be found in the water though. Same goes for the coral, plugs or rock they arrive on can harbor cysts though.

I also have a 20g long setup for corals. They and any invert which has a hard surface where cysts can encyst, gets the full fallow period. If it’s a healthy frag with only live tissue, I cut off the base, dip and after a week or so, it goes into my display.
