Quiz for BAR members...when I scrape them off the glass and they lay in the sand bed, are they still alive? Should I remove them or save them for the crab?
Are you trying to eradicate the starfish population, or enjoy the harlequin shrimp(not a crab) for the long term? If trying to eradicate, yank out the starfish. If you want to enjoy the harlequin, leave them inThis is really where the harlequin shrimp are useful. Not because they eat all the starfish but because they scare them all onto the glass where you can grab them and toss them.
