Lesser spiny eel Care Guide

The Lesser Spiny Eel is an intriguing aquatic species known for its moderately challenging care requirements. It is essential to replicate its natural habitat and provide appropriate tank conditions to ensure the well-being of this very rare and semi-aggressive species.

Tank Setup

The Lesser Spiny Eel requires a tank environment that accommodates its bottom-dwelling behavior. A substrate that mimics sandy or muddy riverbeds is ideal, as it allows the eel to burrow, which is a natural behavior. The tank should include plenty of hiding spots such as caves, rocks, and driftwood to cater to its moderately territorial nature.

A tank of at least 30 liters is advisable to house a single eel, but larger tanks are necessary if keeping a school. The minimum school size for a comfortable community is three eels. Maintain environmental conditions with a pH range of 6.0 to 8.0 and a temperature range of 22°C to 28°C.

Water Quality and Maintenance

Regular maintenance is essential for preventing stress and illness in the Lesser Spiny Eel. Since the species is of moderate hardiness, maintaining clean water through regular partial water changes and proper filtration is necessary. This will help keep the tank environment balanced and prevent the build-up of toxins.

Feeding

Lesser Spiny Eels are not particularly picky eaters but require a varied diet to thrive. They enjoy a mix of live, frozen, and prepared foods. Suitable diet options include:

• Flakes and pellets for general nutrition
• Bloodworms and Tubifex worms for protein
• Brine shrimp and frozen shrimp for variety
• Daphnia and micro worms for fiber
• Feeder fish, algae wafers, and color-enhancing foods
• Vegetable matter and stick-on tablets
• Freeze-dried foods for convenience

Behavior and Compatibility

While the Lesser Spiny Eel displays semi-aggressive behavior, it can generally coexist with other semi-aggressive species. Avoid housing with very small or timid fish to prevent stress and potential aggression.

Breeding

Breeding Lesser Spiny Eels in captivity can be challenging and requires a well-thought-out environment to mimic their natural breeding conditions. During breeding, their aggression levels slightly increase, so it may be beneficial to have a separate breeding tank to protect other inhabitants.

With diligent care practices and appropriate tank conditions, the Lesser Spiny Eel can thrive in an aquarium and provide an engaging spectacle with its unique behaviors and preferences.
