Hikari Cichlid Excel (Mini Sinking Pellet):

The Low-Level Herbivore Specialist

In the aquarium hobby, while floating pellets are the standard for many African Cichlids, the Sinking variant of Hikari Cichlid Excel is the “connoisseur’s choice.” It is specifically designed for herbivorous cichlids that are reluctant to feed at the surface or for community setups where top-dwelling fish outcompete bottom-feeders for floating food.

This formula maintains the legendary “Excel” focus on wheat-germ and spirulina but delivers it directly to the substrate, catering to the natural grazing instincts of rift-valley inhabitants.

1. Nutritional Philosophy: Targeted for the “Aufwuchs” Grazer

Most herbivorous cichlids, particularly Mbuna from Lake Malawi and Tropheus from Lake Tanganyika, are evolved to graze on algae mats (Aufwuchs) covering rocks.

• The Sinking Advantage: By sinking slowly to the bottom, these pellets mimic the natural feeding position of these fish. This reduces “air-gulping,” a common issue with floating pellets that can contribute to buoyancy problems and digestive stress.

• Digestibility: Because these fish have exceptionally long intestinal tracts, they require a diet that won’t “stall.” The inclusion of high-quality Wheat-Germ provides a natural source of Vitamin E and ensures the food remains mobile within the gut, drastically reducing the risk of “Malawi Bloat.”

2. Technical Composition

The “Mini” sinking pellet is approximately 3.0mm to 3.4mm in diameter. This size is large enough for adults to find easily, yet small enough for sub-adults to masticate without struggle.

Note: The Sinking version typically features a slightly higher protein and fat content than the floating version to account for the denser manufacturing process required for buoyancy control.

3. Key Ingredients & Benefits

• Cultured Spirulina: Provides a high concentration of β-carotene. This is the primary driver for “natural” colour enhancement, ensuring that your fish exhibit deep, lustrous blues and vibrant yellows without the “washed-out” look associated with low-quality fillers.

• Pure Wheat-Germ: Acts as a digestive catalyst. In the fluctuating temperatures of a home aquarium, wheat-germ remains the most reliable plant protein for preventing intestinal blockages.

• Advanced Sinking Technology: Unlike “heavy” sinking pellets that crash to the bottom, Hikari Excel Sinking is designed for a controlled descent. This gives mid-water herbivores a chance to intercept the food before it hits the sand.

4. Physical Performance in the Tank

One of the hallmarks of Hikari’s premium line is water quality management.

1. Integrity: The pellets are bound to stay solid for an extended period. This is vital for “grazers” who may pick at a pellet over several seconds. It prevents the food from dissolving into a fine “dust” that would otherwise fuel algae growth or clog your sponge filters.

2. Palatability: The scent profile is designed to trigger the olfactory senses of rock-dwelling fish. Even the most “reclusive” specimens will usually emerge from their caves once the sinking pellets begin their descent.

5. Feeding Guidelines for the British Hobbyist

• The “Target” Method: If you have a dominant Alpha male guarding the centre of the tank, drop the sinking pellets at both ends of the aquarium simultaneously. This ensures the subdominant fish and females can feed without being bullied.

• Quantity: Feed 2 to 3 times daily. Only provide what the fish can consume within one minute. Sinking food is harder to remove once it enters the rockwork, so “less is more” is the golden rule.

• Substrate Consideration: If you use a very fine sand substrate, ensure your flow isn’t so high that it buries the pellets before the fish find them.

6. The Verdict

The Pros:

• Natural Feeding Action: Perfect for “rock-pickers” who prefer to feed at or near the substrate.

• Bloat Prevention: The wheat-germ-heavy formula is a proven safeguard for sensitive African species.

• Uniform Growth: Sinking pellets often ensure a more even distribution of food among a colony than floating variants.

The Cons:

• Visibility: It is slightly harder to monitor “uneaten” food compared to floating pellets.

• Maintenance: If overfed, sinking pellets can accumulate in “dead spots” behind rockwork, requiring diligent gravel vacuuming during your weekly water change.

For the serious keeper of herbivorous cichlids, Hikari Cichlid Excel Mini Sinking is an essential tool. It respects the biological and behavioural realities of rift-valley fish, providing a premium, vegetable-rich diet that promotes health from the bottom up.
