Repashy Soilent Green 340g – Gel Fish Food for Algae & Biofilm Grazers

Repashy Fish Food Soilent Green is a premium gel diet formulated for freshwater fish that naturally graze on algae and biofilm. Designed for species such as plecos, otocinclus, hillstream loaches, Siamese algae eaters and mollies, this high-quality formula helps support long-term health and natural feeding behaviour.

Each serving provides a balanced blend of spirulina, plant proteins and marine ingredients, helping to support vibrant colour, strong immune function and healthy digestion. The spirulina-rich formula encourages natural grazing behaviour and is well suited to algae-eating species in home aquariums.

The premix is easy to prepare – simply add boiling water, mix and allow it to set. Once cooled, the gel can be cut into cubes or strips for feeding. Before the gel sets, it can also be spread onto rocks or décor to create natural grazing stations.
