Found throughout the world, freshwater gobies are small, bottom dwellers that come in a wide range of brilliant colors. They’re beloved for their intriguing behavior, distinctive appearance, and compatibility with other freshwater species.
Whether you’re looking for the perfect fish to feature in a new show tank or wondering what to add to your freshwater community tank, gobies could be the perfect pick.
In this guide, we’ll explore some of the most popular freshwater goby species and review the basics of freshwater goby fish care.

Gobies belong to the family Gobiidae, one of the largest families of fish with more than 2,000 species spread across over 200 genera.
Most gobies are bottom-dwellers, but they can be found in a wide range of habitats, including coastal marine, brackish, and freshwater environments.
Freshwater gobies, in particular, can be found in both temperate and tropical habitats in Europe, Asia, Australia, and the Americas.
Popular Freshwater Goby Species
Though there are thousands of gobies in the world, not all of them are common in the aquarium trade. Some of the most popular freshwater species include the following:
-
Blue neon goby (Stiphodon atropurpureus) – With their slender bodies, blunted head shape, and bright blue coloration, blue neon gobies are easily recognizable.
-
Bumblebee goby (Brachygobius doirae) – Perfectly suited to nano tanks, bumblebee gobies are known for their small size and black-and-yellow coloration.
-
Peacock gudgeon (Tateurndina ocellicauda) – Named for their vibrant color and peacock-like pattern, these gobies do well in community freshwater tanks.
-
Dragon goby (Gobioides broussonnetii) – Also known as violet gobies, dragon gobies have slender, eel-like bodies with bulbous heads and sharp teeth.
-
Knight goby (Stigmatogobius sadanundio) – Naturally found in brackish environments, knight gobies are adaptable to freshwater and are known for their territorial attitudes and ambush predator feeding style.
Because the goby family is so large and varied, it’s important to select a species carefully, especially if you’re adding gobies to an existing tank.
Make sure you understand the details of freshwater goby care specific to the type of goby you’re planning to stock in your tank, whether that’s blue neon goby care or peacock gudgeon care, so you can create a suitable habitat for your fish.
Setting Up a Freshwater Goby Tank
Gobies are generally small fish, with some species growing less than 1 inch long and others close to a foot in length.
Choose an aquarium appropriately sized for the goby species you select, and don’t forget to consider whether the species is best kept individually or in groups. In either case, it’s often wise to choose the largest tank size you can afford and reasonably maintain.
Generally speaking, territorial species like the knight goby should be kept individually unless the tank is large enough to provide multiple territories.
Social species like blue neon gobies and bumblebee gobies, on the other hand, will appreciate having 3–5 others of their kind in the tank. It’s still important to provide ample space and appropriate decorations, however, so each fish will feel comfortable.
Take the time to research the conditions in your gobies’ native habitat to determine how best to decorate your tank. Many freshwater gobies do well in planted tanks but may need soft substrate to burrow into or rock caves in which to hide.
If the species you choose comes from a tropical climate, you’ll need to install an aquarium heater to maintain your tank within the proper temperature range (generally 72–82°F).
Filtration is essential as well. Many gobies inhabit fast-flowing bodies of water where oxygen levels are high, so consider a filtration system with an adjustable flow rate so you can customize it as needed.
Feeding Freshwater Gobies
Gobies have a diverse range of feeding habits. Some popular species, like blue neon gobies, are grazers, feeding primarily on algae and biofilm.
Others, like peacock gudgeons and bumblebee gobies, are carnivores. Carnivorous gobies feed on small invertebrates like crustaceans and insects in the wild.
In the home aquarium, gobies may accept a variety of commercial foods. Keep in mind that most gobies are bottom-dwellers, so sinking foods are preferred.
A staple diet of sinking pellets or wafers suitable for your goby’s feeding habits (herbivore vs. carnivore) is ideal. It’s also wise to include a variety of live and frozen foods to round out your goby’s diet and provide enrichment.
Gobies tend to eat small, frequent meals in the wild rather than eating a large amount at once. You can recreate this feeding style in the home aquarium by offering small amounts of food 2–3 times per day.
Just be sure not to offer more than your fish can eat in 1–2 minutes and remove any uneaten food after an hour.
Other Freshwater Goby Care Tips
Keeping your freshwater gobies happy and healthy is far from an impossible task, but consistency is key. It will help to start with a suitable setup, giving your tank plenty of time to cycle before introducing any fish.
If you’re stocking the tank with grazing gobies like blue neon gobies, consider adding driftwood or leaf litter, and give the tank extra time to develop natural growths of algae and biofilm for your gobies to feed on.
Most freshwater gobies are compatible with peaceful community fish, though some tend to nip at the fins of long-finned species like bettas or angelfish.
If you’re keeping a group of gobies, aim for an odd number and be sure there are plenty of nooks and caves for the fish to claim as territory in the tank.
Gobies can be kept with shrimp, though some may feed on baby shrimp if the opportunity presents itself.
Final Thoughts
Freshwater gobies make wonderful additions to the home aquarium, and they can be quite entertaining as well.
