Chladoflora mini moss balls are miniature spherical colonies of Aegagropila linnaei algae — each approximately 1 cm in diameter — that form naturally in lakes with circulating currents, which roll them into their distinctive round shape. This pack contains five mini balls, perfectly sized for nano aquariums, shrimp tanks, and foreground planting where standard-sized Marimo would be out of proportion.Chladoflora is one of the most genuinely low-maintenance species in the aquarium hobby. It grows in low light without CO2 injection and tolerates a wide range of temperatures and water conditions. Shrimp graze on the surface biofilm actively. After transit the balls may float — a gentle squeeze underwater releases any trapped air and they will sink.The five-piece set provides immediate foreground detail and natural variety in a small footprint. They can be scattered freely across the substrate, arranged in groups alongside rocks, or used to complement other hardscape elements. Roll them gently between the palms at each water change to maintain their spherical shape and ensure even light exposure.
