Gobies are hardy, amiable, and visible aquarium fish. They get a long well with most other fish. Cleaner gobies, like neon gobies, will interact with other fish in the aquarium, cleaning them of parasites and disease. While other gobies are not cleaners, they still are not aggressive and don’t bother other fish, as they mainly scoot along the aquarium’s rock structures. Tiger gobies are an excellent example of this behavior. They are very visible and highly active. In general, gobies can greatly contribute to the dynamics of an aquarium.
