I have a few pincushion urchins in my large tank and they do an awesome Job on the rocks. I'm thinking about bringing one over to my acro tank to see if it will clean up my rocks some. I'm not to concerned if it picks up a frag now and then but want to make sure it won't eat coral. I found mixed info online and would like to hear from those with who have actual experience. I would move it back to the other tank when cleaning is done so it wouldn't turn to the coral because of starvation.
The tank I would like to clean up a bit.
