    As a harlequin shrimp Lover, i was always looking for a way of providing Fresh starfish for them to feed,
    Since going to the ocean to get starfish is out of the question,
    And fluctuation in tempreture it makes it almost impossible for them to live in the main tank, I'm doing some Experiments on different ways of keeping them alive.

    I was thinking of keeping them in the FRIDGE!!!
    Since the fridge has a stable and low enough tempreture, i'm hoping they make it in there,
    I collected some starfish over the weekend and left 5 in a bottle with enough algea for them to eat,
    and put 10 in the main tank, until now, all the 5 star fish are alive in the fridge and feeding on the algea,
    And almost 80% of the ones i left in the tank, despite the 8hour acclimation, are dead.

    I will get some more water from the sea and keep it in a separate container and do water changes every week, so that they would have a good water condition,
    And we see what happens!

    take the thermometer with you to the beach and see what is the real temperature of the water. If the fridge is set to its highest position, it could work. My fridge can set from +2 to +8. So if the seawater is +8 I can use my fridge easily.

    Our waters range from 12-16 degs Always see this temp range from a fish finder. Hadi I'm thinking this will work easy at room temps in winter time.

    My Fridge is Set on 7 Degrees , And based on what i could see so far, they prefer a bit colder water to warmer.
    So far all of them are happy and feeding on the algea, @Andre@ReefAquatics you are right andre, but you can never trust the tempreture in Capetown ;) it could go up to 25degrees during the day, i've lost many starfishes in winter too,
    But so far, i'm very happy with the way its going,
    5/5 are alive so far, which is the biggest success rate i ever had so far.

    Cool, that's great, the pleasures of living by the coast, now just a miracle to get our waters up to 25 deg then we can be as lucky as the Durban oaks.

    I'm hoping those are still the harly's from us ?

    What i used to do , took a rather large starfish and yes i know its cruel but i stuck it in the freezer, every now and then i chopped off a little piece and fed it to my harlequin shrimp. Its cruel but the shrimp needs to survive.

    Hadi if you look carefully by the pools where we spoke about on the weekend you'll find some larger orangey red stars during low tide way back of the island...

    I also do that with the cushions,
    But harlequins don't like the frozen ones very much, they take it if they haven't been eaten for 3-4 days
    That's why I want to look for an option to keep them alive

    I should spend more times by those pools!
    I haven't seen anything else beside cushions and snails!

    So I have a pair of harlequin shrimp and @hadiosbourne has seen them. I have always added cushion stars to my display and let the shrimp feed as they would in the wild. I would collect at low tide in pools that temp has increased due to the heating of the sun. I do still see that the stars will sit at the top of the tank where the water cools quicker. Never had a problem. I collect at moullie point as there are plenty of cushion stars or even in muizenberg where the water is a bit warmer.

    Thats right, But where your tank is placed, the tempreture fluctuation is very little,
    my guess is that they are sensetive to tempreture fluctuation,
    Thats why they like the fridge tempreture,

    100% success rate so far!!
    It's been 10 days now, And they look extremely happy!
    I didn't even change the water or add oxygen to it ( which I probably should have)
    I will collect some more stars, fresh algea and some water and will start doing water changes every 2weeks.
    Will keep you posted
