Tropical Hi-Algae Discs XXL Fish & Invertebrate Food 125g

Tropical Hi-Algae Discs XXL are large-format sinking wafers formulated for herbivorous and omnivorous bottom-feeding fish and invertebrates in tropical aquariums. Designed for species that graze on algae and plant matter as a core part of their diet, these discs deliver a concentrated algae-rich feed directly to the substrate where plecos, otocinclus, larger loaches, and freshwater invertebrates naturally forage.

Algae-Forward Formulation

The high algae content makes these discs well suited to species that rely heavily on plant-based nutrition, including common and royal plecos (Hypostomus and Panaque spp.), bristlenose catfish (Ancistrus spp.), and algae-grazing loaches. Rather than a general sinking wafer, these are targeted at fish whose nutritional needs skew heavily toward vegetable and algae matter.

XXL Disc Format

The larger disc size reduces competition at feeding time by giving multiple fish or a single large specimen a sustained food source to graze on. The wafer holds its shape in water, breaking down gradually rather than dissolving quickly and clouding the tank. This makes it practical for tanks with strong flow or active inhabitants.

Sinking Wafer Feeding Behaviour

These discs sink immediately and stay on the substrate, mimicking the natural feeding position of bottom-dwellers. This is particularly relevant for nocturnal species — place a disc shortly before lights out to ensure shyer fish get consistent access to food without competition from mid-water or surface feeders.

125g Pack Size

The 125g pack suits established community setups or tanks with multiple bottom-feeding species, providing a useful supply without the wafers losing freshness before use. Store in a cool, dry place with the pack sealed after each use.

A practical, species-appropriate staple feed for any tropical setup housing herbivorous bottom-dwellers — no guesswork, just a consistent dietary foundation for the fish and invertebrates that need it most.
