Repashy SuperFoods Super Green — Vegan Algae Gel for Herbivorous Fish & Invertebrates, for Sale UK

Repashy Super Green is one of the most precisely-formulated specialist aquatic feeds available — a 100% vegan green algae gel premix designed specifically for true herbivorous and algae-grazing freshwater fish and invertebrates. Where most "algae" foods contain at least some animal protein for palatability, Super Green takes a fundamentally different approach: no animal products or byproducts whatsoever, with Spirulina Algae and Chlorella Algae as the dominant ingredients. The result is a clean algae-based formula that genuinely matches what specialised algae-grazers eat naturally — meaningful for species whose digestive systems evolved specifically for plant cell wall breakdown rather than processing animal proteins.

What makes Super Green particularly worth seeking out is the genuine biological precision. True herbivorous and algaevorous species (Tropheus cichlids, Petrochromis, Ancistrus and Otocinclus plecos, specialised algae-eating shrimp and snails) have notably longer digestive tracts than omnivorous species — adaptations for extracting nutrients from tough plant cell walls. These specialist feeders can have genuine difficulty processing animal proteins and fats, which simply aren't a significant part of their natural diet. Super Green provides them with appropriate algae-dominated nutrition without compromising their digestive specialisation.

This is genuinely distinct from Repashy's other green-focused product, Soilent Green, which also contains substantial algae but includes whole fish, squid, and krill ingredients. Soilent Green suits omnivorous algae-eaters that benefit from mixed nutrition. Super Green suits strict specialist herbivores that need pure plant-based feeding. Choosing between them depends entirely on the dietary requirements of your specific species.

Available in 85g, 170g, and 340g sizes. Currently sold out across all variants — restock when available.

What Is Super Green?

Super Green is a "vegan algae gel premix" — a precise product category worth understanding:

The vegan formulation means Super Green contains zero animal ingredients — no fish meal, no krill, no insect meal, no animal-derived proteins or fats whatsoever. This isn't a marketing claim; it's a fundamental product design decision targeting species that genuinely benefit from pure plant-based nutrition.

The "green" focus reflects the dominant algae content. The first two ingredients are Spirulina Algae and Chlorella Algae — both genuinely concentrated algae sources rather than supplementary additions to plant-protein bases. Supporting plant ingredients include Pea Protein Isolate, Rice Protein Concentrate, Alfalfa Leaf Powder, Stabilized Rice Bran, Dandelion Powder, Coconut Meal, Ground Flaxseed, Schizochytrium Algae, and Dried Seaweed Meal.

The "gel premix" format means you receive Super Green as a fine powder that you reconstitute with boiling water before feeding. Powder premixes have dramatically longer shelf life than pre-made gels and let you prepare exactly what you need per feeding. The format also enables presentation flexibility — gel cubes for varied feeders, shredded for shrimp colonies, or whole slabs for grazing species.

Super Green vs Soilent Green — The Critical Choice

This is the most important section for keepers comparing Repashy's green-focused products:

Soilent Green contains high algae content AND whole fish, squid, and krill ingredients. It's designed for omnivorous species that benefit from algae nutrition combined with animal protein. Most "algae-eating" fish like plecos, snails, and many shrimp species are actually omnivores — they eat algae preferentially but benefit from occasional animal protein. Soilent Green suits these omnivores well.

Super Green contains pure algae and plant ingredients with zero animal content. It's designed for true specialist herbivores where animal protein would actually be detrimental. These species' digestive systems are specifically adapted for plant-only nutrition and can struggle with the meat content in mixed formulas.

Which should you choose? Depends on your specific species:

• For Tropheus and Petrochromis African cichlids: Super Green. These rift-lake cichlids are strict herbivores with digestive specialisations that can't handle high-protein meat-based foods. Misfeeding causes serious health issues including "bloat" — a frequently fatal condition. Super Green is genuinely the right choice for these species.
• For Ancistrus and Otocinclus plecos: Either works, but Super Green is preferable for strict algae-grazing specialists like Otocinclus. Ancistrus tolerate either food well.
• For mixed pleco tanks: Soilent Green or Bottom Scratcher likely better — most popular plecos (including bristlenose) are omnivores benefiting from mixed nutrition.
• For algae-eating shrimp: Super Green works well, particularly for specialised algae-focused shrimp species. Most popular shrimp (Caridina, Neocaridina) are omnivores and accept either food.
• For algae-eating snails: Either works for mystery and nerite snails. Super Green is the safer choice if you want pure vegan feeding.

What Species Specifically Need Super Green?

Super Green's design specifically targets species where vegetarian feeding matters. These include:

Tropheus cichlids. Tropheus duboisi, Tropheus moorii, and other Tropheus species from Lake Tanganyika are strict aufwuchs (algae and microorganism) grazers. They're notorious for developing fatal "Tropheus bloat" when fed high-protein animal-based foods. Super Green provides the appropriate plant-only nutrition these specialist cichlids need.

Petrochromis cichlids. Similar to Tropheus — strict algae-grazing rift-lake cichlids that require pure plant nutrition. Super Green is essential rather than optional for serious Petrochromis keepers.

Otocinclus catfish. Tiny algae-grazing catfish that struggle with animal-protein foods. Super Green provides appropriate plant-based supplementation when algae growth in the tank isn't sufficient.

Some Ancistrus species. While bristlenose plecos are largely omnivorous, some specialist Ancistrus species do better on pure plant-based feeding. Super Green is the safer option.

Specialist algae-eating shrimp. Some specialised algae-eating Caridina varieties and other algae-grazing shrimp species do well on Super Green's pure plant formulation.

Algae-eating snails. Mystery snails, nerite snails, and other gentle algae-grazing snails accept Super Green willingly. Particularly useful for snail-only tanks or quarantine setups.

Mbuna cichlids (some species). Some Lake Malawi mbuna species lean strictly herbivorous. Super Green provides appropriate nutrition for species where animal protein causes issues.

How Super Green Compares to Other Repashy Products

Super Green is part of Repashy's specialist aquatic range. Here's how it relates to alternatives:

• vs Soilent Green: Both contain high algae content. Soilent Green adds whole fish, squid, and krill. Super Green is pure vegan. Choose Soilent Green for omnivorous algae-eaters. Choose Super Green for strict specialist herbivores.
• vs Bottom Scratcher: Bottom Scratcher is an invertivore formula (no fish meal but substantial invertebrate protein) for fish/inverts that eat aquatic invertebrates. Super Green is for herbivores. Different species categories entirely.
• vs Community Plus: Community Plus is a balanced omnivore formula with both plant and animal ingredients for mixed community tanks. Super Green is specialist pure-plant feed for strict herbivores. Different audiences.
• vs Morning Wood: Morning Wood is a terrestrial detritivore supplement for isopods and similar species. Super Green is aquatic. Different ecological domains entirely.
• vs Bug Burger: Bug Burger is for terrestrial invertebrates and is used to enhance live feeder insects before they're fed to reptiles. Super Green is for direct feeding to aquatic herbivores. Different applications.

How to Prepare Super Green

Super Green preparation differs slightly from other Repashy gels — the ratio is 1 part powder to 3 parts water rather than the 1:2-3 used for other Repashy products.

Standard Gel Preparation

1. Bring water to a rolling boil (kettle, stove, or microwave)
2. Pour boiling water into a heatproof bowl
3. Add powder at a ratio of 1 part powder to 3 parts boiling water
4. Stir vigorously until smooth and fully combined
5. Pour into a mould, container, ice cube tray, or flat dish
6. Allow to cool and set at room temperature — typically 10–20 minutes
7. Cut into pieces, shred for shrimp, or use as whole slabs for grazing species

Alternative Microwave Method

Repashy's own preparation guidance includes a microwave alternative:

1. Mix 1 part powder into 3 parts water in a microwave-safe container
2. Stir until blended
3. Microwave until it starts to boil
4. Remove and stir
5. Let cool, or pour into mould
6. Set at room temperature until firm

Adjusting firmness: Use less water for firmer gel (better water stability), or more water for softer gel (easier for small species to consume). Most keepers find the 1:3 ratio works well for the majority of feeding applications.

Presentation Options

• Cubes: Good for general feeding to fish
• Shredded: Ideal for shrimp colonies — gives them plenty of surface area to graze on
• Whole slabs: Excellent for Tropheus and similar grazing cichlids that prefer biting pieces from a larger food source — mimics their natural aufwuchs grazing behaviour
• Suction cup feeders: Attach gel pieces to enclosure walls for arboreal-grazing applications

Storage and Shelf Life

• Unopened powder: Store in original sealed packaging at room temperature. Long shelf life — check expiry date on packaging.
• Opened powder: Seal tightly and store in cool, dry place. Use within 12 months for optimal freshness.
• Prepared gel: Treat as fresh food. Refrigerate sealed for up to 2 weeks. Freeze for up to 6 months for longer storage.

Pro tip for serious keepers: Prepare large batches and portion into ice cube trays for freezing. Each cube becomes a single feeding portion that defrosts quickly when needed — dramatically more convenient than daily fresh preparation.

Size Variants — Which Should You Buy?

Super Green is available in three sizes:

• 85g (3oz): Trial size — perfect for testing acceptance with specific species. Makes approximately 340g of gel after preparation. Suitable for small specialist setups or testing acceptance with picky algae-grazers.
• 170g (6oz): Standard size — the mid-range option for regular feeding. Makes approximately 680g of gel. Reasonable for keepers with established Tropheus tanks or similar specialist herbivore setups.
• 340g (12oz): Value size — bulk option for serious keepers, multi-tank setups, or breeding operations. Makes approximately 1.4kg of gel. Most cost-effective per gram for keepers feeding Super Green regularly across multiple aquariums.

The 1:3 powder-to-gel ratio means each gram of dry product produces 3 grams of finished gel — significant feeding volume from compact storage.

Why Pure Vegan Matters for Specialist Herbivores

For keepers wondering whether the "no animal ingredients" claim genuinely matters:

Digestive system specialisation. True herbivores like Tropheus and Petrochromis have notably longer digestive tracts than omnivorous fish — adaptations for breaking down plant cell walls and extracting nutrients from algae and plant material. This specialisation means they're less efficient at processing animal proteins and fats. Pure plant-based feeding aligns with their evolutionary adaptations.

The "bloat" issue in Tropheus. Tropheus cichlids are notoriously prone to a condition called "bloat" — a frequently fatal digestive disorder triggered by inappropriate feeding (typically high-protein animal-based foods). Strict plant-based feeding dramatically reduces bloat incidence. For Tropheus keepers, pure herbivorous feeding isn't preference; it's survival-critical husbandry.

Long-term health outcomes. Even species that can tolerate occasional animal protein may show better long-term health, more vibrant colouration, and reduced disease incidence when fed appropriate species-specific diets. Many serious cichlid breeders consistently report better outcomes when matching food to species biology.

Avoiding palatability shortcuts. Many commercial "algae" foods include fish meal or other animal proteins specifically to improve palatability — animals find them tastier so they eat more. Super Green doesn't take this shortcut, which means picky individuals may need encouragement initially. The trade-off is appropriate species-specific nutrition rather than just palatability.

Who Should Buy Super Green?

Ideal for:

• Tropheus cichlid keepers (essential rather than optional)
• Petrochromis keepers
• Otocinclus catfish keepers
• Specialist algae-grazing herbivore setups
• Strict herbivorous Mbuna cichlid keepers
• Algae-focused shrimp and snail tanks
• Anyone running specialist herbivore-only tanks
• Aquarists wanting genuinely vegan fish feeding options

Not ideal for:

• Omnivorous community fish — try Community Plus instead
• Invertivorous species — try Bottom Scratcher instead
• Insectivorous reptiles — try Grub Pie instead
• Terrestrial isopod setups — try Morning Wood instead
• Tanks where Soilent Green's mixed formula better suits omnivorous algae-eaters
• Marine aquariums (designed for freshwater applications)

Tips for Optimal Use

Introduce gradually. Some specialist herbivores need time to recognise Super Green as food, particularly individuals that have been fed mixed diets. Try smaller portions initially and increase as acceptance develops.

Watch for proper algae visibility. Super Green has a notable green colour from the spirulina and chlorella content. If you don't see the characteristic green tint in your prepared gel, double-check the powder hasn't been compromised by moisture or age.

Match presentation to feeding behaviour. Grazing species (Tropheus) benefit from whole slabs they can bite from. Open-water feeders prefer cubes. Shrimp and snails prefer shredded forms with more surface area.

Combine with other appropriate foods. Even for strict herbivores, varied feeding generally produces better outcomes than single-food diets. Combine Super Green with fresh vegetables (blanched zucchini, spinach, etc.), spirulina-based pellets, and other appropriate plant-based options.

Don't overfeed. The high algae content means small portions deliver substantial nutrition. Feed amounts that get consumed within reasonable feeding periods and remove uneaten portions before they foul water.

For Tropheus specifically: Multiple small daily feedings work better than single large meals. This mimics their natural grazing pattern and reduces bloat risk.
