Poll. Do you quarantine your fish and corals?

I wanted to name drop https://notafeesh.com for those who want qt of fish or corals for them.

If you want to do yourself these are great protocols. I do not recommend most use formalin. It is not for beginners and is dangerous. https://notafeesh.com/blogs/blog/how-we-quarantine-fish

They are suppppper helpful and informative. But the quarantine procedures can save all the tank mates both your existing fish or new fish. And corals.

If you have questions I can help or get you the answers.

So poll. Do you qt fish? Corals? Inverts?
