Overview
The candy stripe goby is a big sand-sifting goby that spends its day mouthing the substrate for food, much like a small eartheater. It is best with a little experience.
Did you know
The candy stripe goby feeds by taking mouthfuls of sand and sorting out edible particles, detritus and invertebrates inside its mouth. The clean grit falls back out through its gills, so a fine sand bed is its working tool rather than decoration.
Caring for the candy stripe goby
The candy stripe goby grows to about 3.9 in (10 cm) and stays busy. Give it at least 29 gal (110 L) with a long, open sand bed. The bed should be deep, soft and fine, so the goby can sift it without scratching itself. Add some smooth wood or rock for structure, and keep the flow gentle to moderate.
Keep the water warm at 75 to 82°F (24 to 28°C) and close to neutral, with a pH of 6.5 to 7.8. Feed sinking foods, frozen bloodworm and small meaty items that reach the floor.
It is mostly peaceful and social, though males can be territorial over a chosen patch. Keep a single fish or a small, well-spread group, and give it plenty of floor space. Choose calm mid-water tank mates that will not beat it to a meal.
The candy stripe goby is amphidromous. It breeds in fresh water, and the larvae drift out to sea to develop. There is no reliable record of it spawning in aquariums.
Good to know
Awaous flavus is a member of the family Oxudercidae and one of the larger gobies kept from fresh water. The name flavus means yellow or golden and refers to its warm body tone and stripes. It is also known as the flavus sand goby.
In the wild
The candy stripe goby works the sandy and muddy beds of coastal rivers along the Atlantic side of northern South America. It ranges from Venezuela and the Guianas to Brazil, in fresh and very lightly brackish lower reaches. The water is warm and the bottom is soft and open.
