Blue Mandarin - Synchiropus splendidus
Avg Size 3" Females & up to 3.5-4" Males
Females are a little more expensive as they are harder to get.
Males have a tall thin mast on the back fin behind their head & the females sport a shorter, cropped & rounded fin.
These peaceful little fish are normally ignored by other fish as they don't have normal fish characteristics that make them seem like a threat. Also know they have a bad tasting, toxic to fish, slime coat which is a big part of their defense against predation.
Never, ever keep 2 male Dragonets in the same tank as they will fight to the death! You can keep multiple females or a single male with multiple females. Beware of the fact that some male Dragonets could have been improperly housed with unsuitable tankmates & may have had their long dorsal fin nipped off so it "looks" like a female! Folks, this is way too common. Buy only from a reputable source like AquaCorals & know what you're getting!
My Dragonets do not leave my facility until they are eating frozen PE Mysis Shrimp (PE = Piscine Energestics)! This usually takes a week so you know they are fully rested as well as eating when they arrive to your home!
Feeding Dragonets: My Dragonets are trained to eat PE Mysis Shrimp. I do not use nor recommend any other brand Mysis! See the PE Mysis Shrimp page for more details as to why.
Feed Every Day - Once A Day. Only feed your Mandarin PE Mysis Shrimp. They do not need anything more. I do not recommend adding pods or using brine shrimp etc. You risk introducing pathogens to your tank and neither are as nutritious as PE Mysis Shrimp.
How To Prepare. Start by thawing the amount to feed in cold tap water. A clean bathroom size paper cup works well for most. Once thawed, pour/strain through a net (a 3 inch net works great for this) & rinse with cold tap water. Add clean tap water to your cup & backwash the Mysis shrimp into the water. Add any other foods like flake & frozen Calanus to the Mysis. I suck up this "soup" with a clean turkey baster & broadcast feed the mix into the tank.
Do NOT Target Feed. Please, understand they are reclusive eaters meaning they won't want to eat in front of you until they associate you with food. Do not chase your AquaCorals Dragonet(s) around trying to target feed them and do not stay near your tank trying to see them eat as that only makes them want to hide (or they will just sit still) & you're defeating the purpose - them eating. Trust me when I say my Dragonets know full well what PE Mysis shrimp is & when hungry, will chase after it no matter how many other fish you may have competing for it!
Give your new Mandarin about a week before looking at them hard. If they are eating they will maintain their plump body condition or they will look thinner. Thinner is noted by a concave belly as well as seeing a horizontal rib line that runs down the length of their body. A well conditioned Dragonet will be brightly colored & it's body rounded out all the way to it's tail whereas a malnourished Dragonet will be concave above & below this rib line, pictured below.
