    I have an asterina starfish outbreak. I added a harlequin crab to my tank Saturday. He's moving about a bit, but the starfish seem to have multiplied rather than been depleted. I read they eat up to 15 per day. When should I see him begin to eat, or are they nocturnal?

    Also after I scrape them from the glass, do i need to siphon them up, or can they stay in the sand?

    Thanks in advance!

    You added a harlequin SHRIMP or a crab?

    When you add the harlequin the stars know they are in trouble and try to escape. That is why you see more.

    Which one does it look like? Cause the crab won't help you.

    Someone else will have to answer that one. I've never been able to put any shrimp in my DT because I've always had fish that lust after them.

    How long have you had it? If it’s newly added to the tank might take a few days to feel comfortable enough to go venturing out and eating during the day.

    So from what I’ve read, harlys only eat the tube feet of the starfish, not the whole thing. I’ve always thought “won’t all of the left over mass of starfish cause a nutrient spike”? Very very cool shrimp, however.

    when you see all the start fish on your glass then you know they run away from the shrimp. I have one available if anyone need him.

    This 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.

    Does your's actually eat the starfish? Have you seen it do so in the night or day?

    It's not like peppermint shrimp, file fish or copperband butterfly with aptasia. They either eat starfish or they starve to death. They don't eat anything else.

    I don't have one but I've used them before

    I got him Saturday and the starfish population only seems to have exploded. I haven't seen him eat, and today he's missing.

    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?

    They are still alive. The shrimp will get them.
