Frequently asked questions
How is it different from the barcheek goby?
It is generally larger, with bolder and more contrasting markings, and comes from the Yellow and Yangtze systems rather than the wider range of R. giurinus. Care requirements are essentially the same.
Can I keep a group?
Yes — a group of three to five works in a roomy tank with multiple shelters. Add an extra hiding place beyond the number of fish to diffuse territoriality.
Will it eat small tankmates?
It will eat anything that fits in its mouth, including small shrimp and fry. Choose tankmates of similar size and bottom-dwelling confidence.
Can they climb out of the tank?
Yes — gobies can scale wet glass and plumbing. Any gap at the lid, overflow or tubing entry must be sealed or screened.
