Hikari Cichlid Excel (Medium Pellet):

While the “Mini” variant of Hikari Cichlid Excel is the go-to for juveniles and dwarf species, the Medium Pellet is the specific workhorse for the mature, larger inhabitants of a Rift Valley setup. In the British hobby, where Lake Malawi “Mbuna” and Lake Tanganyika herbivores are perennial favourites, this food is often cited as the primary defence against digestive ailments.

This in-depth guide explores why the Medium pellet is more than just a larger version of its smaller sibling, focusing on the nutritional requirements of adult herbivorous cichlids.

1. Nutritional Philosophy: The “Long Gut” Challenge

Herbivorous cichlids possess a unique physiological trait: an exceptionally long intestinal tract. In the wild, they graze on “Aufwuchs” (algae mats) all day. This high-fibre, low-density diet requires a long transit time for nutrient extraction.

Feeding these fish a standard “meaty” pellet can lead to Malawi Bloat—a condition where high-protein, low-fibre food essentially stagnates and ferments in the gut, causing lethal swelling and bacterial infection.

• Wheat-Germ Power: Hikari uses the highly digestible heart of the wheat kernel. It is rich in natural Vitamin E and ensures that the food moves steadily through the digestive tract.

• Pure Spirulina: Cultured to provide high-intensity colour enhancement. It targets the “chromatophores” (pigment cells) of the fish to keep yellows, oranges, and blues vivid and natural.

2. Technical Specifications & Guaranteed Analysis

The Medium pellet is designed for adult fish, typically those exceeding 15 cm (6 inches) in length.

3. Physical Characteristics: Size and Buoyancy

The Medium Pellet measures approximately 5.0 mm to 5.5 mm. This size is strategic:

• Efficiency: For a large adult Mbuna or Tropheus, a “Mini” pellet is often too small to be worth the energy of a surface strike. The Medium size allows the fish to feed efficiently with fewer “gulps.”

• Floating Type: Like the rest of the Excel range, this is a floating food. This is vital for cichlid keepers because it allows you to observe the “pecking order.” You can immediately see if a subdominant fish is being bullied away from the surface and adjust your feeding locations accordingly.

• Structural Integrity: These pellets are designed to absorb water and soften into a “fleshy” texture without disintegrating. This ensures that even the messiest eaters don’t leave a cloud of fine dust that would otherwise clog your mechanical filtration.

4. Feeding Guidelines for Large Colonies

When managing a large, aggressive cichlid colony in a 300+ litre tank, your feeding technique is as important as the food itself.

1. Broadcast Feeding: Rather than dropping all the pellets in one spot (where the “Alpha” will guard them), scatter the Medium pellets across the entire surface of the water.

2. The 60-Second Rule: Large cichlids are incredibly fast. Only feed as much as they can consume in a minute. Overfeeding is the #1 cause of nitrate (NO3​) spikes and “bloat” issues.

3. Temperature Awareness: If your tank temperature rises during a British summer, your fish’s metabolism will spike. Conversely, in cooler water, digestion slows. The wheat-germ in Excel makes it a safer choice during these transitions than high-protein alternatives.

5. The Verdict

The Pros:

• Specialist Health: Specifically engineered to stave off the dreaded “Malawi Bloat.”

• No Artificial Dyes: Colours are enhanced through spirulina and wheat-germ, meaning your fish won’t look “unnaturally” bright.

• Value: Because it is nutrient-dense and highly digestible, you actually need to feed less by volume than with “budget” brands.

The Cons:

• Species Specific: While great for omnivores, this is not a suitable primary diet for carnivores  who require much higher raw protein.

• Surface Tension: In very high-flow tanks, floating pellets can occasionally be swept into the overflow or surface skimmer before the fish can get to them.

For the keeper of large, majestic African herbivores, Hikari Cichlid Excel Medium is the gold standard for long-term health. It bridges the gap between the wild grazing diet and the requirements of a closed aquarium system, ensuring your fish stay as healthy as they are colourful.
