The Hyphessobrycon Eques 'Long Fin' is a captivating variant of the Serpae Tetra, renowned for its distinctive long fin extensions that add an elegant touch to its appearance. This tropical freshwater fish, originating from South America, is a popular choice for community aquariums. Let's explore the key features and care requirements of the Hyphessobrycon Eques 'Long Fin':

Appearance:

• The 'Long Fin' variant features extended fins, especially the dorsal and anal fins, creating a graceful and flowing effect.
• Its body displays the characteristic red and black coloration of the Serpae Tetra, with a striking contrast that enhances its visual appeal.

Water Conditions:

• Temperature: Maintain a tropical environment between 72°F to 78°F (22°C to 26°C).
• pH Levels: Aim for slightly acidic to neutral water conditions, ideally between 6.0 to 7.5.
• Water Hardness: Keep water hardness in the soft to medium range, around 5 to 15 dGH, replicating their native habitat.

Tank Size and Setup:

• The Hyphessobrycon Eques 'Long Fin' is suitable for community tanks and should be housed in a tank of at least 20 gallons.
• Provide hiding spots among plants, rocks, and driftwood, creating a well-decorated environment. The extended fins add an aesthetic appeal to the aquarium.

Tank Mates:

• Serpae Tetras are generally peaceful but can display fin-nipping tendencies, especially during feeding.
• Choose tank mates carefully, focusing on other mid-sized and non-aggressive species like tetras, rasboras, and peaceful cichlids.

Feeding Habits:

• The 'Long Fin' variant shares similar feeding habits with the standard Serpae Tetra. It is an omnivore, accepting a varied diet.
• Offer high-quality flakes, pellets, and supplement their diet with live or frozen foods such as brine shrimp, bloodworms, and daphnia.

Care and Maintenance:

• Regular water changes are essential to maintain water quality, and consistent monitoring of parameters with reliable test kits is recommended.
• Pay attention to the fin-nipping behavior, and ensure that all tank mates receive sufficient food to reduce aggression during feeding.

Schooling Behavior:

• Serpae Tetras, including the 'Long Fin' variant, are schooling fish. Keep them in groups of at least six to mimic their natural behavior and reduce stress.

Breeding Behavior:

• Breeding the Hyphessobrycon Eques 'Long Fin' in captivity can be challenging.
• Provide a separate breeding tank with fine-leaved plants, where the adults can lay eggs. Once the eggs hatch, feed the fry with small, nutritious foods.
