Jelly Bean “What”?

[Saltees]

These Jelly Beans are taking over the undersides of my rockworks, biobricks, even on the sides of euphyllia. They feel like jelly beans when you squeeze them…rubbery texture. Some have visible intestines in them. Wonder are they friend or foe?

 

[IKD]

I would guess a sponge/tunicate of some sort. I assume they don’t move on their own. Don’t see any reason to fear them.
