Tropical Green Algae Wafers are sinking wafers made for herbivorous and omnivorous plecos, other algae-eating fish and compatible bottom feeders. They are a dry prepared food, not a frozen food. Each wafer is approximately 2.5cm across and is designed to stay together in water so rasping fish can feed in the way their mouthparts are built to work.
The formula combines seaweed, spirulina and ketapang leaf with vegetable proteins and other ingredients. Tropical describes it as a complete ornamental fish feed, but suitability still depends on the animal being fed. Match the portion and feeding routine to the species, size, age and other foods in the aquarium.
| Pack | Net weight | Practical fit |
|---|---|---|
| 100ml | 45g | A smaller pack for trying the food or feeding a modest number of bottom feeders. |
| 250ml | 113g | A useful regular-use size for established home aquariums. |
| 1L | 450g | A larger supply for multi-tank fishkeepers or animals that take sinking food regularly. |
| 5L | 2.25kg | A bulk option for fish rooms, breeders and other high-use settings with suitable dry storage. |
Select the pack in the size control beside the basket. Larger packs offer more food, but they only make sense when the contents can be kept sealed, dry and used while fresh. The current price and stock shown for each size are not repeated in this permanent description.
The manufacturer’s primary audience is herbivorous and omnivorous Loricariidae: the catfish family that includes many plecos and bristlenose catfish. Their underside mouths and rasping behaviour make a stable sinking wafer a practical format. Other algae-eating fish and omnivorous bottom feeders may also take the wafers when the ingredients and wafer size suit that species.
Tropical also lists the food as a complementary option for omnivorous bottom-feeding fish and for suitable freshwater or marine crustaceans. That is not a promise of compatibility with every shrimp, crab, snail or bottom-dwelling fish. Offer a small test portion, observe whether the animals can feed normally, and keep the rest of the diet appropriate to the species.
Although this is a vegetable-focused algae wafer, the declared composition also includes fish, molluscs and crustaceans. It should not be described as vegan or as a purely plant-based food.
The current manufacturer declaration lists derivatives of vegetable origin, including at least 2% ketapang (Terminalia catappa), vegetable protein extracts, algae, fish and fish derivatives, molluscs and crustaceans, cereals, yeasts, oils and fats, and minerals including 1% zeolite. The algae portion includes at least 4% Ascophyllum nodosum and at least 3% Spirulina platensis.
| Declared component | Amount | What it tells you |
|---|---|---|
| Ascophyllum nodosum | Minimum 4% | A brown seaweed included in the algae blend. |
| Spirulina platensis | Minimum 3% | A cyanobacterium widely used in prepared aquarium foods. |
| Ketapang leaf | Minimum 2% | Declared as Terminalia catappa in the vegetable ingredients. |
| Zeolite | 1% | Listed by the manufacturer within the mineral ingredients. |
Ingredient lists can be revised by a manufacturer. If the physical container supplied differs from this page, use the label on the container as the final reference, especially where an animal has a known ingredient sensitivity.
| Constituent | Declared level |
|---|---|
| Crude protein | 45% |
| Crude oils and fats | 6% |
| Crude fibre | 5% |
| Moisture | 10% |
The declared nutritional additives per kilogram are vitamin A 28,000 IU, vitamin D3 2,000 IU, vitamin E 120mg and vitamin C 585mg. The manufacturer also lists iron, zinc, manganese, copper, iodine, selenium and molybdenum compounds, together with colourants and antioxidants. These are label values, not claims that the food treats disease or corrects a diagnosed deficiency.
The manufacturer advises small portions several times a day. For nocturnal fish, place an appropriate portion into the aquarium after the lights go out so faster daytime feeders are less likely to take it first. The exact amount cannot be reduced to a universal number of wafers: a juvenile bristlenose, a large pleco and a group of shrimp have very different requirements.
A whole 2.5cm wafer may be more than a small animal or lightly stocked aquarium needs. Split a wafer before feeding when a smaller portion is appropriate. In a busy community tank, use more than one feeding point so a dominant fish cannot guard the entire ration.
The wafers are designed to remain intact in water rather than immediately breaking into fine particles. That gives rasping and grazing animals time to feed, but it does not make overfeeding harmless. Any uneaten food can add organic waste, so portion control and routine maintenance still matter.
Green Algae Wafers are prepared food for compatible animals. They do not remove algae from the aquarium or replace lighting control, water changes and nutrient management. They are not a medicine and should not be presented as a cure for growth, digestive or water-quality problems.
| Food | Main difference | When to consider it |
|---|---|---|
| Green Algae Wafers | Vegetable-focused 2.5cm sinking wafers with spirulina, seaweed and ketapang. | For compatible grazing fish and bottom feeders that benefit from a stable rasping format. |
| Pleco tablets | A different sinking tablet formula aimed specifically at plecos. | When comparing ingredient profiles or tablet formats for a species-specific feeding plan. |
| 3-Algae tablets | A tablet-format algae food with a different formulation. | When the animal or aquarium setup is better matched to smaller tablets. |
| Fresh vegetables | High-moisture supplementary food with variable nutrition. | As part of a varied plan for species known to accept suitable vegetables. |

Fishkeepers planning a Loricariid diet can also use our pleco care guide as a starting point, while remembering that requirements vary between species.
Keep the container tightly closed in a cool, dry place away from humidity, direct sun and aquarium splashes. Use a clean, dry utensil if one is needed, and do not return damp food to the tub. Follow the best-before and batch information printed on the supplied container.
The four pack sizes share the same product page so you can choose the appropriate amount without navigating duplicate listings. For current packing, delivery and service details, see the delivery information page before ordering.
Identity, composition, analytical constituents, additives, feeding guidance and available pack sizes were checked against the current Tropical Green Algae Wafers product record. The product label supplied with the food remains the final reference for the batch in your hands.
