    Hey FDB, what do you feed your harlequins? I know that they eat cushion stars as that's what I feed them. But you're in Pretoria, and they're not readily available there?

    My Harlequins take silversides, hake and most starfish that does not scare them. (Fast moving starfish for example scares them).
    I have seen them eat a co-inhabinat fish that died.
    I have not seen it myself, but apparently there are people who feed thier harleys shrimp food mix.

    I must just add that i do dose my tank with vitimins and stuff.

    Wow... that's wild. All the literature that I've read says that they eat only starfish, and even then only specific types. I think you may have a very lucky find there. Here's a cool article on an absolutely fascinating creature. Harlequin Shrimp

    he he he.
    Yea i have read the literature too. Very amusing. :)

    Lucky find?
    Can't be.
    They both eat the diet above and i bought them months apart.

    I do however beleive that if you overfeed them starfish, that yes, they won't take anything else. (I will also not eat just veggies if i get steak and chips everyday)

    Is a diet of just hake good for them? No. Sure it's not. But if they eat it out of thier own, why not?
    I keep a starfish in the refrigium.. I can see when they get hungry as they start to swim towards the inlet pipe (the one from the refrigium) a lot. Then i gooi a silverside or hake and they chow it. Sometimes, they take it a day or two later (fresh ones).
    I give them a peice of starfish once a month. The rest of the time, they nibble on fish.

    These days however, my female (Ok... the dominant one) clown steals ALL the silversides and feed them to my ... Excuse me... HER.. Anemone
    &^%$#@!

    Hey... I'd rather have the veggies than the meat an 'taters anyway, but I get your drift.

    Here's a pic of my harlequin chowing down on a star burger. Check how they have specialised appendages just for sticking into the starfish to hold them. They also use these to wedge under the starfish to dislodge it from it's holdfast.

    Oh my soul... I think I have found the creature that I want the most in my tank... Does that even make sense? LOL!

    Those things are absolutely INCREDIBLE! Seriously, how could people not want them in a tank? Are they safe with other shrimp?

    They are safe with other shrimp.
    They do bully hermits, but they are harmless. (Well.. Not to seastars)

    By the way, we took another photo of them eating a silverside fishy yesterday.
    The female is still carrying her eggs.

    Sweet. Where did you get them from? I've never seen them in any of the stores before.

    I read that article now and the guy says that his don't eat anything but starfish? Maybe yours are the exception to the rule? I seriously think that they are a MUST have for the new tank. I can't wait.

    Here we pay R200 for them...I think they can go for as high as R250.

    I would not advise buying them without a supply of starfish , even after what has been said above. I still am not convinced this is not an isolated case where they have had to adapt to eating something that they dont naturally eat. Its the same as telling someone to go and buy a Mandarin because yours eat pellets where as more than 90% of the time they will only eat live foods.

    I understand this. Don't worry, I do plenty of research before buying anything marine related! I'm going to look into these guys very seriously. Even if I have to Pay for someone living on the coast to go and catch some of those little starfish for me every month or so. I just think they are some of the most beautiful things I've ever seen!

    "I still am not convinced this is not an isolated case where they have had to adapt to eating something that they dont naturally eat"

    Like fish eating flakes?
    They don't naturally eat flakes, but they learn to eat them.
    Some fish need to be taunted into taking non live foods.

    Now that the same is being done for Harlequins, something is fishy?
    :)

    The process is simple.
    Buy one harley.
    Buy a big sea star.
    Put Harley into tank.
    2 days later, give harley a 1square CM Seastar tentacle.
    Wait 2 weeks.
    Drop a piece of hake (1 square cm) in the tank.
    If it did not touch it, remove it.
    2 days later, drop hake in the tank.
    If it did not touch it, remove it.
    Wait 2 days.
    Drop hake in tank.
    If not touched, remove.
    Feed harley starfish tentacle.
    Repeat cycle.

    As soon as he takes the hake/silverside:
    Entice it with fish on week 2 and push it to just under week 4. Never wait more than 4 weeks to feed it seastar. That is the max.

    Pretty soon, harley takes the hake on week 2 and starfish on week 0. So you feed it starfish about once a month. and fish too. (But you will see it stealing stuff every now and again if you feed hermits or nennies silversides)

    And no.
    The above is not starving them.
    Mine are dead happy. Molting, breeding, etc.
    :)

    Yes most fish do learn to eat flakes and prepared foods but some never do, I would classify Harlequins in the same catagory as these fish as specialised diet requirements.

    If there were more recorded cases of them eating anything else maybe... but, one isolated recorded case in the world (being you) does not justify this as fact that they will eat anything other than starfish. I would not say that you are starving them, but I reckon they would have had to come close to doing so the first time to have to look for an alternative food source.

    I have had mine for well over a year and they have never shown any interest in any other food stuff that I have tried to push on them...and yes they had not eaten for a while. I will try your method above and see if there is any success this time around.

    Very interesting topic. These shrimps are by far the most beautiful creatures I saw (besides the creatures with two long legs).
    Two weeks ago, i was told an importer here in CT sells these shrimps.
    I said, I would love to get me some, but starfish?
    The guy said, the importer feds them with normal food. Got his details and I will have a chat with him. Let you guys know about the result.
