The Yellow Filter Feeding Cucumber, scientifically known as Colochirus robustus, is a unique and intriguing invertebrate that adds both color and functionality to marine aquariums. With its bright yellow appearance and filter-feeding behavior, the Yellow Filter Feeding Cucumber is a captivating addition that enhances the ecological balance of your reef tank.


The Yellow Filter Feeding Cucumber features a vivid yellow coloration on its elongated body, which is adorned with numerous feathery appendages called tube feet. These tube feet play a crucial role in filter-feeding, as the cucumber extends them into the water to capture tiny suspended particles and phytoplankton. They typically grow to a size of around 3 to 4 inches, making them suitable for small to medium-sized reef setups.


Known for their peaceful and non-intrusive nature, Yellow Filter Feeding Cucumbers are generally compatible with most reef-safe fish and invertebrates. They are best kept in well-established reef aquariums with ample live rock and a matured ecosystem, as they require a constant source of food particles in the water to sustain their filter-feeding behavior.


Feeding the Yellow Filter Feeding Cucumber is unique, as they primarily rely on filter-feeding to obtain their nutrition. They will extend their feathery tube feet into the water to capture small particles, phytoplankton, and detritus. It is essential to ensure that the aquarium has sufficient planktonic life and tiny food particles to support their feeding habits.
