My LR is covered in wierd slime :scared:
It's the only one that looks like this. The other ones look fine while this one looks moldy. Its covered in a white mold like substance. It was like that at first but i wasn't concerned until a piece of it fell of and left a trail of green slime !!!!
What is it and should i throw the LR away?
Heres a few pics of it:

sometimes if a mushroom or other soft coral takes to long in the mail it will look like that. Thats my guess.

Is it harmful to the other LR? Is it contagious?

I took it out and it smelled really bad!!! I threw it away, but I'm curious what happened to make it so?

For the future, you should be able to take out the rock wash in salt water--I use the water from the tank (water change) and scrub with a brush. The rock should be ok to use again once cleaned. If you already threw it out and can retrieve it, you will have to recure it. It appears to be a sponge that died.

Some sponges grow like that, I have some that is yellow but it is on my rock not detached.

Did you cure that rock before you put it in there?
The white stuff is called "die back" . The sponge and stuff on live rock grows in layers like skin. It gets too much air exposure when collected and transported. Basically what your seeing is a blistering sunburn. The bad things in a nutshell are; thats way too much dead stuff, it suffacates the beneficial bacteria inside the rock.
