goby care sheet

This care sheet covers a variety of goby species, including:

  • Yellow watchman goby
  • Clown goby
  • Diamond watchman goby
  • Rainford’s goby
  • Neon goby
  • Tiger watchman goby
  • Yasha goby

Overview

Scientific names: Crytocentrus cinctus, Gobiodon citrinus, Valenciennea puellaris, Koumansetta rainfordi, Elactinus oceanops, Valenciennea wardii, Stonogobiops yasha, Valenciennea strigata

 

Gobies are part of the largest fish families and are comprised of some of the smallest vertebrates, like the dwarf pygmy goby. One unique trait of gobies is that their pelvic fin has formed into something like a suction cup, which helps secure them onto rocks. Some gobies have a symbiotic relationship with some species of shrimp.

 

Typical appearance and behavior

  • Have a fused pelvic fin that acts like a suction cup
  • Gobies can change gender from male to female and female to male
  • Most gobies are bottom dwellers
  • The neon goby, aka “cleaner goby,” helps remove parasites from larger fish
  • Yasha gobies are well known for their symbiotic relationship with some species of pistol shrimp
  • Some goby species spend their day sifting through sand and creating borrows

Building your habitat

Water health -

Provide proper filtration to ensure optimal water quality to help maintain health. Low, moderate to strong water circulation should be provided to mimic water currents and high oxygen levels found in the goby’s natural habitat. Stable water quality (pH, ammonia, nitrate, nitrite) and water temperature are critical to the health of aquatic life. If you are unsure of your water quality, bring a sample to Petco for free testing. The addition of a protein skimmer can aid with maintaining great water quality and high dissolved oxygen levels. An aquatic heater should be used to stabilize water temperature, ensuring it does not fluctuate more than +/-2 degrees in a 24-hour period. The specific gravity should remain stable. Do not allow specific gravity to fluctuate more than +/-0.001 in a 24-hour period

Décor – Live rock can provide places to hide as well as a natural food source while also enhancing biological filtration

 

What do gobies eat?

A well-balanced goby diet consists of:

  • Small crustaceans known as copepods, amphipods, ostracods and polychaete worms
  • Live baby brine shrimp called artemia
  • Pellets, flakes and freeze-dried or frozen brine shrimp or mysis shrimp
  • A varied diet will help ensure proper nutritional balance

 

Things to remember when feeding your goby:

  • Feed them small amounts two to three times daily, no more than they will eat in 1 to 2 minutes
  • Thaw frozen food before feeding

 

Goby care

Maintaining great water quality with regular water changes and adequate filtration is important to help keep your gobies healthy

  • Daily: Check filter, water temperature and other equipment
  • Weekly: Test water quality at least once a week
  • Weekly to monthly: Change 10 to 25% of the total volume of water every two to four weeks or as needed; change filter media monthly

Avoid overcrowded conditions, which are a major cause of stress and disease

Health Issue Symptoms or Causes Suggested Action
Health IssueFin rot Symptoms or CausesFrayed or disintegrating fins; the base of the fins usually reddens. Suggested ActionImprove water quality; consult your local aquatic specialist or aquatic veterinarian for treatment.
Health IssueMarine ich or marine velvet Symptoms or CausesCysts on fins, gills and skin; rapid breathing; excess skin mucus or pale skin; fish rubs against hard objects or swims erratically. Suggested ActionQuarantine fish immediately and use a commercial parasite remedy; complete a water change, freshwater dips can help dislodge the parasites; consult your local aquatic specialist or aquatic veterinarian for treatment.
