Do you have Asterina starfish, they eat coraline

As previous poster my asterina snails do clear a lot of coraline. Also I noticed when it gets think it chunks/peels off but that is mostly on my plastic overflow chambers

Do you test iodine? Also, do you have a tuxedo urchin?

Crabs will also peel it off.

Agree on Crabs. I do not recommend asterinas unless you enjoy seeing 4 become 400 in no time while they much on your zoa
Pin cushion and pencil urchin will consume it
