Bluestreak Goby Care Guide for Beginners

Bluestreak Goby Introduction


The Bluestreak goby is one of the most popular fish amongst hobbyists. Once you add this tiny friend to your community tank, you will be glad to see the colourful objects moving from corner to corner. It is an active and fun fish to complement your overall fish tank community.


The Bluestreak goby is also called the Blue Striped Goby. It has a greenish-yellowish-blueish body with noticeable blue streaks on the head and fins.

These streaks are the main focal point of this tiny buddy. Each specimen might have slightly different streaks of hues which allow you to name your goby individually.


Bluestreak Goby Overview


The Bluestreak goby is also known as the pennant glider, blue and goby, and blue band glider goby, and the golden-head sleeper goby.


Gobbies are fun to take a look at. They will dig a burrow into the substrate to stay and wait for their prey. They also dig in the sand to sleep at night. The burrow is also their natural protection when they want to hide from their enemies.

Bluestreak Goby Characteristics


Besides the blue streaks, the other noticeable characteristic of the Bluestreak goby is the cylindrical body shape with multiple dorsal fins. The rear body tends to be whitish with a blue sheen. The colour of their gill plates can change to a bright golden yellow depending on the water condition, their diet, as well as their mental health.


These goby fish can grow up to 18 cm in the world. But in captivity with good care, they can reach up to 10 to 12 cm. So, when you attain the particular sized goby in your aquarium, you don’t need to worry since they will be just fine.


True habitats


The gobbies flock to the coastal waters of Tanzania. They are true bottom dwellers, usually swimming a few cm from the substrate in pairs.

Or, they usually sit on the substrate nearby their own burrow. They usually do everything in pairs. But it is also possible that they split up for a while for hunting or else, then rejoin again.


They have the habit of hiding under the burrow. At night, they will go under the burrow to enjoy their quality time. Then they will emerge again from the substrate in the morning.


The pairs are usually together and protect each other. They also have burrows that they mark as their own territories. Both genders prefer larger mates. They will swap partners for satisfaction.


The Bluestreak goby can also be found across the Indo-west Pacific, from East Africa to Japan, to Lord Howe Island. Domesticated, you can find the fish in the local market.


There is a good reason why they spend most of their time on the substrate. It is because they want to reserve the live food resources that live in the sand. They want to make their stomachs full.



Bluestreak Goby Tank Requirements & SetUp/Tank Guides


The gobbies need an adequate size of the aquarium to thrive. If it is for a small group, 30 gallons should be sufficient for your gobby buddies.


You might want to multiply the gallons if you add more tank mates or more specimens of gobbies. The larger the aquarium, the better, since your gobby pets will be able to create as many


Gobbies could possibly jump to escape from your aquarium. Although they are not good jumpers, you won’t want to take the risks. Keep the aquarium safe with a tight-fitting lid or mesh screen.


It will effectively prevent your bluestreak goby from jumping out of the aquarium.


The good thing about the substrate and bottom part of your aquarium is that the gobbies are not aggressive toward others. So, they might be able to share their burrows with other species if you introduced them much earlier.


They make a great contribution to the community tank. The tank with deep fine sand and well-maintained water will be the ideal quality for them.


They dig the burrows with their intelligence. They have their own strategies for making burrows. I can say that it is a fish with a lot of interesting characters. There will always be new stuff that you can find when you monitor your fish.


Make them active by maintaining the sand and oxygenation. Since they dig a lot, you might want to consider if you want to add crustaceans or else to the bottom part. Your goby will tend to dump sand a lot on these creatures. Some of them are okay with this. But some invertebrates can be a bit sensitive to this kind of provocation.


The key to maintaining the health and wellness of your fish is in the water, oxygen, and sand quality. We mentioned the first two terms back in the last paragraph. Now, to the sand. You must make sure that your tank has hosted mature live sand before adding your goby there.


Their bottom-feeding habits can be a fun spectacle to watch. But it does come with a takeaway you need to consider. Thanks to their habits, there’s a risk of suffering from parasites. Therefore, it is best to deworm them first.


Hardy fish


The Bluestreak goby is indeed a hardy fish. But they require proper maintenance in the tank in order to survive. Although you are a beginner, you can actually manage this fish as long as you follow the guide thoroughly. They can strive if you provide them with the proper source of food, water changes, and tank maintenance.



Bluestreak Goby Tank size


A 30 gallon tank should be enough for a small group of gobbies. If you have a single goby as a pet, you could use your nano tank as well.


But on most occasions, the goby is pretty much happier in the medium-sized planted tank. The nano tank might have no space left because of the plants and other tank mates.


A group of 5 to 8 gobies can thrive in a 30 gallon tank. You will need to multiply the size of the tank for more dwellers. If you are going to make groups of these fish, you could add more plants and hiding places to provide these fish with private places to enjoy their time.


The Lighting


You can choose from a wide array of lights for your own aquarium. The Neon Goby does not usually have complicated specifications for aquarium lighting.


But due to its nature, it is safe to assume that they prefer more shades. Therefore, adding dense planting could be the right move to provide the best environment for your bluestreak goby.


But you will also want to consider your aquatic plants as well. You will need to provide an adequate amount of lighting to support them in growing and thriving.


The Tank Décoration



The planted tank will be the right host for your bluestreak goby. The bright blue and yellowish color of the goby will work well together with the plants in your aquarium. The substate recommended for the fish and its group is using commercial aquarium soil. The soil must be black since it will make the fish outstanding. Not to mention that the soil will provide enough nutrition for them to survive.


You could also add as many décorative pieces as you need. I’d suggest focusing on Blackwater soil since it provides a great environment for them, especially when they need their burrows for convenience and protection.



Water quality


The other specification that you need to maintain is the water quality. Any slight changes and fluctuations in the water in your tank can hugely affect the fish’s physical health and mental health. You must maintain the balanced parameters of water and its temperature. The goby fish will live at a good temperature of around 73 to 75° Fahrenheit.


The pH level should be between 8 and 8.5.


Ensure you purchase the best quality aquarium filtration from your pet suppliers. The water flow is necessary to maintain your good health and wellness. Since this comes from the shallow water in nature, the best way to make them thrive for a long time is by replicating the characteristics of their natural habitat.



Bluestreak Goby Tank Mates


The Bluestreak gobies are usually indifferent towards their other tank mates. But you don’t want to tag them with aggressive fish since they could be bullied.


Your goby little friend is a bottom dweller. So, you don’t need to worry if they are living with the mid and top dwellers. For their tank mates, I’d rather suggest some fish from the Goby family as well, such as the Bumble Bee goby. Or, the other fish that can make perfect tank mates are Tetra fish, loaches, Siamese, and so on. These fish are also cool with shrimp. Don’t worry, they won’t eat your pet shrimp.



Bluestreak Goby Diets/Food/Feeding



This fish is carnivorous. So, the diet is all about animals. You can feed this feed with favourite items like small fish fry, insects, small worms, crustaceans, and other stuff. You can also feed them with fish pellets. Bloodworms can be their best protein resource.


Bluestreak Goby Breeding guidelines


Your gobies will breed in small caves. As mentioned, they usually move with their pairs. Therefore, you might want to separate a couple of gobies from the other tank mates. They will lay their eggs in their small caves and other places. Some specimens might be a bit picky about the lighting conditions. Once the eggs are there, you will need to maintain the water, lighting, and environmental conditions.
