Added some red grape macro algae to my display tank yesterday (thanks cat) and just noticed that there are 2-3 brittle stars climbing on it. I was thrilled at first, as these guys hardly ever come out of the live rock, but of course my next question is, is this a problem in any way? Lights are out, by the way, just moonlights going at the moment.
Have any of you seen this before?
