Red Lipstick Goby – Sicyopus rubicundus
Introduction:
The Red Lipstick Goby (Sicyopus rubicundus) is a captivating species that stands out due to its striking red-orange markings around the mouth and its peaceful nature. Growing to a size of around 2-3 inches (5-8 cm), this small but colorful goby is a favorite among aquarists who want a unique addition to their freshwater or brackish tanks. The Red Lipstick Goby is known for its active foraging habits and bright coloration, making it a charming addition to well-maintained aquariums.
1. Natural Habitat and Behavior
The Red Lipstick Goby is native to Southeast Asia, where it is commonly found in freshwater and brackish streams and rivers with rocky substrates. This species thrives in slow-moving to moderate currents and is often seen near the bottom, where it feeds on detritus, small invertebrates, and algae. In the aquarium, it displays typical goby behavior: staying close to the substrate, darting into hiding spots, and scavenging for food. It is peaceful and tends to stay away from larger, more aggressive tank mates.
2. Aquarium Setup
The Red Lipstick Goby prefers a freshwater to slightly brackish environment. A 10-20 gallon tank is ideal for housing a small group or a single specimen. The tank should have a rocky or sandy substrate to mimic its natural environment and offer hiding spots. Incorporating driftwood, caves, and plants into the aquarium setup will allow the fish to find shelter and feel secure. Maintain a temperature range of 74-78°F (23-26°C) with a slightly acidic to neutral pH of 6.5-7.5. A gentle filter or water pump should be used to ensure a moderate flow, simulating their natural habitat.
3. Diet and Feeding
The Red Lipstick Goby is omnivorous, feeding on a variety of foods. In the wild, it consumes small invertebrates, detritus, and algae. In captivity, it will eat high-quality algae wafers, spirulina, and small live or frozen foods such as brine shrimp, daphnia, and bloodworms. As bottom feeders, they often forage for food along the substrate. It’s recommended to feed small portions twice a day, ensuring they have enough access to food near the bottom of the tank.
4. Compatibility with Other Fish
This species is peaceful and works well in community aquariums. It can be housed with small, non-aggressive fish, such as tetras, rasboras, and other small gobies. They may become territorial around hiding spots, so ensure plenty of shelter and space within the tank. It’s best to avoid keeping them with large or aggressive fish that may outcompete them for food or harass them. As a bottom-dweller, they are compatible with other peaceful bottom-feeding species, like Corydoras catfish.
5. Common Challenges and Tips
- Territorial Behavior: While peaceful, Red Lipstick Gobies may exhibit territorial behavior, especially around their hiding spots. Providing ample caves and hiding spots in the tank can reduce potential conflicts.
- Sensitive to Poor Water Quality: Like many gobies, they are sensitive to poor water quality, so it is essential to perform regular water changes and maintain optimal water parameters.
- Dietary Needs: Ensure a varied diet that includes both plant matter (such as algae wafers) and animal protein (such as small live or frozen foods). This will keep them healthy and vibrant.
Conclusion
The Red Lipstick Goby (Sicyopus rubicundus) is an attractive and peaceful fish that can thrive in well-maintained aquariums. Its vibrant coloration and active, bottom-dwelling habits make it a fun addition to community tanks. With the proper care, including a balanced diet, suitable water conditions, and compatible tank mates, the Red Lipstick Goby will flourish and become a highlight of your aquarium.
