Yes. The main diseases that have a stage that can use hard surfaces as a vector are Ich and Velvet. Anything hard acts as a substrate for the tomont stage to attach to and encyst.
Anything wet gets the QT .
Snails and hermit crabs — full 76 days in a full QT- heater, air stone, cycled HOB. I use sand and a big hunk of live rock too . There are 120 assorted snails and 18 hermits in here
Shrimp and crabs- until they molt. But if you put anything new in the tank after they molt but before you move it, then you need to wait until next molt. Be careful- very susceptible to osmotic and temp stress for about a week after molt
I use little 2 gallon totes for shrimp. Heater, air stone for circulation. No need for a filter
Urchins and sea stars- good news!! No QT, but make sure you rinse several times in saltwater into a bucket before you put them in DT. This’ll wash off any freeswimmers
Anemones- don’t get encysted with tomonts, but do trap a lot of water internally that could have ich or velvet freeswimmers. QT 16 days fallow until the velvet freeswimmers starve to death.
I also QT chaeto in a bucket with a light and air stone for circulation for 16 days, in order for velvet freeswimmers to starve . Any small snails I notice get picked off first. Then I do a dip in coralRX to get rid of pods. They have a hard shell that can be encysted upon. Then 16 days in the bucket
