The Mandarin Goby (Synchiropus Splendidus) is quite simply one of the most breathtaking marine fishes ever to hit the hobby. Its entire body is made up of blue, orange and green alternating line. They commonly go by the name, mandarin goby, despite not being a true goby at all. Its seldom called true name, is the mandarin dragonet.

This fish is heavily collected mainly from the Indo-Pacific. Despite its common appearance at marine pet stores all over the world, it has an abysmal survival rate in our aquariums. We will see why later on.

As far as temperament goes, they are very peaceful fish. They can be hostile towards members of the same genus such as its close cousin, the psychedelic dragonet. If you're interested in a pair of mandarin dragonets, look for a mandarin with an elongated first spine (a male) and look for one without (a female) and put them together.

Fully grown mandarins come in a about 4 inches in length. A 30 gallon aquarium has enough space for a single specimen, only if they're accepting prepared foods. They don't eat. This is because they only feed on live copepods. Therefore, they need a tank full of live copepods, something like a 75 gallon established aquarium. In an aquarium that large, you'd never have to feed them. They will live off available copepod populations without wiping them out.

With some time and a lot of effort, mandarin fish can be trained to accept prepared foods, even pellets.First, you need adult live brine shrimp. They are receptive to live brine shrimp so getting them to eat it is a task that will take care of itself. Next, you're going to mix in some frozen brine shrimp with the live ones during feeding. If they start taking frozen brine, you're almost home free. Since brine shrimp is nutritionally poor, we need to get to feed on something like mysis shrimp or krill.

As before, introduce some mysis shrimp with the frozen brine shrimp when you feed them. If you can get them on a frozen mysis shrimp diet, you've completed the task. Offer them some krill and a good pellet after that.

But wait, thats just one problem out of the way. They are painfully slow feeders. Every single one of their tank mates will eat twice as fast as a mandarin. There are three ways to solve this problem. You could blast food into the tank to ensure the mandarin gets some. Or, you can spot feed it with the use of a pipette. Lastly, you can find a bottle with an entrance only big enough for the mandarin and stuff some food in there.

All three options can work, but its up to you to choose one.
