Purple sponge. Keeper or not?

 

Unless it's growing over things and overtaking them, I'd leave it be.

 

ive read alot that this sponge can become invasive but they sure are pretty!

 

I had to trim it back some already, I had some small red feathers growing on that same rock and it covered it over. But; I was just checking the senses on it, I will continue to keep an eye on it.

It is very pretty, my phone cam doesn’t do the bright purple color justice.
