How do you care for the hi-fin red banded goby?

Peaceful; territorial with its own kind.

Feeding

Carnivore.

May refuse food for several days after arrival; feed twice daily (LiveAquaria).

Tank and special needs

Plan for at least 38 litres of water (the care sheet says 10 US gallons).

Sand bed; lid.

Why this care level

Moderate per LiveAquaria; shy feeder at first.

Corals and invertebrates

None.

Which tankmates suit the hi-fin red banded goby?

Best with a pistol shrimp (Alpheus randalli); avoid boisterous tankmates.

Suggested order in a mixed tank: add early, with the first peaceful fish.

More than one hi-fin red banded goby

Only as a mated pair, or two juveniles added together. A third hi-fin red banded goby is usually driven out.

Other fish

Checked against the other 59 fish in this guide, assuming a tank big enough for both. Individual fish differ, so treat this as a starting point.

Take care (1)

These checks follow the reasons fish and invertebrates clash: same species or genus, similar shape, mouth size, temperament, food, burrows, tank size and the order they are added. Individual animals differ; every source agrees on that.

Quarantine and health

Standard.

New fish are the most common way disease gets into a reef tank. Quarantine every fish in a separate tank before it joins the display, and choose a method that suits its tolerance of copper.

Captive-bred or wild?

Wild-caught.
