Urchin - New Tank

[RaymondL]

I sold an established tank that had inverts in it: snails, hermit crabs and a tuxedo urchin. These inverts will be put into a new home (I'm in the process of setting up the new tank and moving over the contents of the old tank to the new). I'm hoping the inverts won't have an issue with the new set up. Obviously, it will be much cleaner - new substrate; however same old rock.

If anyone would like to share some tips that'll be great!

If the rock is coming from an established tank and is going directly from old system to new system with only being out of water a short period of time I would not worry at all about it. They will be fine.
