Yes I do, always!
But I do the TTM and dips on my corals just a quicker time frame.
Corals and inverts are as we know it not a carrier of the deceases but sure can have it on them same as you take out a rock from a sick tank to a healthy tank or just equipment/tools like a net or pump.
The transfer of deceases can be made easily.
I don't treat the inverts with anything and use just two 10 gallon tanks for that.
My corals do go in a frag tank and will be dipped on arrival and every 4/5 days after that for two months before they will even see my grow out frag tank.
Some say over kill but to me and many other hobbyist this is going to be the norm as you just can't trust anything anymore.
Oh yes.......... my fish do know as they went through the same quarantine room so they know protocol.:rolleyes:
