The Captive Bred Green Mandarin Dragonet are sold as male and female, if one is sold out be sure to check the other. We are unable to offer bonded pairs at this time.

Our Biota Captive Bred Mandarins offer a hardy and sustainable alternative to wild-caught specimens with easier care requirements. Trained on a diet of Live and Frozen foods, your Mandarin can graze naturally on Pods during the day and fatten up on frozen foods at feeding time. See below for detailed diet information.


Disclaimer regarding gender of the Captive Bred Mandarin Dragonet

We at AlgaeBarn will try our hardest to accurately identify the gender of the Mandarin Dragonet. Since these fish are small and the males can sometimes show aggression towards other males, their dorsal fin can sometimes be slightly damaged (which will heal with time). We may accidentally send the wrong gender and it may show with time. We do not guarantee the gender of the mandarin Dragonet.

    I got one of these little guys, he came well packaged. Also after settling in for a few days I caught him eating frozen brinshrimp. So they are set even at there small size to be ready to live a long and healthy life in our aquariums with out having to risk them starving to death or training them yourself. They also send a free thing of pods so during that settling in time he can eat his regular food.

    • Eric,

      We are glad that they are eating frozen food! We really want the Mandarin fish to be a sustainable aquarium fish, similar to clowns! We really appreciate your review. Let us know if you have any questions!

    Many thanks! My female blue mandarin dragonet is simply beautiful and she’s now acclimating very well in my quarantine system. She’s eagerly eating live copepods from the population I maintain in that tank as well as finely diced frozen foods and frozen copepod blends. She’s very active and the coloration is amazing!

    Your packaging was excellent and she arrived seemingly with very little stress. I didn’t realize she would come with free pods and ocean magik which was awesome as I had just used up my previous pod club order so this was a great way to boost the pod count in the quarantine tank and introduce her to that tank.

    Many thanks! I may get a bonded pair at some point in the future.

    These are exactly what they say, 3/4 inch long. I received mine and drip acclimated her. For the first day appeared to be doing well. But with all the live rock I have haven’t seen her again. I keep hoping she will show up but nothing so far. I would recommend starting them in a small tank with a small amount of live rock so that you can keep an eye on them until they get larger. Algae Barn has the best products. I cant ask for better service. Thank You

    Although shipping was fast, mine never accepted any prepared food while in QT. Unfortunately she didn’t make it a week in QT. There went $80…

    I got a little female in December of 2017. She has done really well in my system. They do come very small, so my little girl took a trip from my refugium, through the separate sump and the return pump, into the main display. Then a week later she escaped the display through the overflow box, back to the sump. I put a sponge over the line from the refugium to the sump and have housed her in the refugium ever since her wild rides. Clearly these little captive bred fish are hardy if she could go through all of that and survive. I am letting her get bigger before I add her to the main display so she doesn’t go through the overflow box teeth again. She is doing great in my refugium and growing steadily on pods.

    I bought a pair of mandarins about three weeks ago. They really do arrive as small babies and I’ve kept them in a acclimation box, containing some rock rubble, inside my reef tank so I can monitor their feeding and keep them out of harms way until they grow a little more. I was prepared a head of time with the recommended food… frozen calanus, frozen brine, fresh hatched brine, TDO chroma b1 and b2 size and lastly added on my own, Reef Nutrition R.O.E. I’ve also added tens of thousands of pods to refugium and directly into the box and continue to hatch bobs daily. They are fed a little variety of food multiple times a day.
    These lil captive bred mandarins are thriving and growing daily. They hunt all day and then sleep side by side when the light go out. Would advise for an experienced reefer and a mature tank. Good job Biota and thanks Algae Barn.

    While the description says your fish will be smaller than 1″, I wasn’t ready for just how tiny this thing was. First, I thought it might be dead, as it was curled up at the bottom of the jar. It wasn’t. Then, I figured this thing was going to die on its own, or get eaten by something in the tank. I put the fish in my tank in the evening, and within 20 minutes, it was scooting around picking off pods from rocks and gravel. At night, I figured the fish would hide. Nope. Picked a depressed spot in the sand bed right out in the open and laid there. It also lost most of it’s pigment, and turned a pale color to blend in.

    Needless to say, the fish scoots around all day long picking off pods. I only started my tank in March, but have a fairly established refugium, no skimmer, and have been “feeding” the tank pods at least once a month. I know the description says it will eat other foods, but my fish has had zero interest in doing so. Perhaps because it’s natural food source is abundant?

    Anyhow she’s growing quickly, and despite my fears, doesn’t appear to be at risk in my tank.

    Arrived on time, well packaged. Very tiny fish, was eating Pods, and Can O’Cyclops. I had it in a Isolation box with pod soaked rocks and covered to shaddow the light away. Sadly, it only lived about 3 weeks. I can’t explain it, everything seemed to be going well. More money down the drain in this hobby for me.
