The Mandarin goby, or Pterosynchiropus splendidus), is a popular fish among saltwater aquarists, but it’s best for more advanced hobbyists for certain reasons. It’s a colorful fish that’s sure to be pleasing to the eye, but there are some things you should understand about this particular species if you want to include it in your tank.

The following guide to the Mandarin goby will help you determine whether this species is worth adding to your saltwater aquarium.

 

Is the Mandarin goby reef safe?

Not only are Mandarin gobies reef-safe, but they tend to thrive best in a reef tank. As a member of a peaceful species, your Mandarin goby won’t go after your tank’s coral or invertebrates beyond the copepods you feed them.

Mandarin goby food and diet

The Mandarin goby’s diet is carnivorous but varied. This species prefers copepods over other foods, but it’s also possible to feed this fish various amphipods, polychaete worms, ostracods, artemia (live baby brine shrimp), or frozen Mysis or brine shrimp.

Mandarin goby FAQs

How big of a tank does a Mandarin goby need?

Your Mandarin goby should have a tank that’s at least 50 gallons or bigger. Additionally, you should have a one- to five-gallon refugium and a minimum of 50 pounds of live rock.

How big do Mandarin gobies get?

Mandarin gobies reach around three inches in length when fully grown, with Mandarin gobies taking approximately 14 months to reach sexual maturity.

Why are Mandarin gobies hard to keep?

One of the challenges that come with caring for Mandarin gobies is their feeding habit. They like eating copepods more than anything else, which are small crustaceans. The main reason for this is that it can be hard to maintain a sufficient number of copepods to keep Mandarin gobies alive.

Mandarin goby price

The price of a Mandarin goby will depend on the specific colors, size, and other factors, but they’re a relatively affordable saltwater fish that shouldn’t cost much to add to your tank. On average, you’ll find this species on the market for around $30 to $40, but some places will sell them for much higher.

Mandarin goby facts

The following are some interesting facts you may not have known about the Mandarin goby:

  1. These gobies go by many names, including the Green Mandarin fish, Mandarin dragonet, Psychedelic fish, and the Striped Mandarin fish.
  2. One fish you don’t want to keep with a Mandarin goby is a scorpionfish, which is this goby’s primary predator.
  3. Instead of scales, the Mandarin goby has a unique defense mechanism in the form of mucus on its surface, which keeps both parasites and predators away.

What other fish are the best tank mates for the Mandarin goby?

Mandarin gobies get along well with other fish and won’t likely cause any problems for them. However, they can get a bit aggressive with members of their own species, particularly when you have two or more males in a tank. You can prevent this by giving them plenty of space or keeping a breeding pair instead.

Otherwise, you can keep this fish with many others, such as:

  • Coral Beauties
  • Firefish
  • Green Chromis
  • Clownfish
  • Watchman gobies
