The "goby ruby spotted fish" typically refers to the freshwater species Rhinogobius rubromaculatus, which is characterized by its reddish-brown body with vivid red spots, especially prominent on males. It also features deep red and blue hues on its fins with delicate white edges and can reach a length of 4–5 cm (around 2 inches). These gobies are found in Taiwan's freshwater streams and are popular in aquariums due to their active, peaceful nature and unique appearance.
Physical characteristics
Body: Reddish-brown with distinct, vivid ruby red spots that are more intense in males.
Fins: Males have particularly striking dorsal and pectoral fins with deep red and blue coloring, often with delicate white fin edges.
Size: Typically reaches 4–5 cm (about 1.5 to 2 inches) in length.
Habitat and behavior
Native habitat: Found in Taiwan's freshwater mountain streams and floodplains.
Aquarium behavior: Known for being active and peaceful, with a tendency to hop along the substrate.
Diet: Carnivorous, feeding on small organisms like brine shrimp, as well as frozen foods, flakes, and algae.
Compatibility: Good for nano tanks, but should not be kept with larger, aggressive fish that might eat the babies or fry.
Scientific name
The most likely species is Rhinogobius rubromaculatus.
A similar-sounding but different saltwater species is Trimma rubrum, also known as the Red Spotted Goby, which is found in marine reefs.
