5 LUFFY Shrimp Balls - Instantly Purify Water for Shrimps: Beautiful & Easy Live Plant: Provide micro-nutrients for Shrimps to Feed on SMALL IN SIZE, BIG IN BENEFITS --- Live plants are highly advantageous for shrimp tanks, but it is important to find just the right aquatic plant. Luffy Nano Marimo Moss Balls are perfect for your freshwater aquarium housing dwarf shrimp, crayfish and all other shrimps because they provide incredible benefits to both the shrimp and the water. These exotic spherical plants do everything from entertaining your pet shrimp to absorb harmful toxins and nitrates present in your aquarium water. HELP PREVENT UNWANTED ALGAE GROWTH --- There is no better way to combat algae than with algae. Marimo moss balls are not really moss, but an algae that requires all of the same nutrients as other undesirable types of algae. Because your bright green Luffy Nano Marimo Moss Balls are sucking up all of the necessary nutrients, invasive algae will not be able to survive in your shrimp tank. The nano shrimp balls help eliminate current algae and prevent new algae from growing back. ABSORB HARMFUL TOXINS & PROVIDE OXYGEN --- Similar to other aquatic plants, marimo balls absorb certain substances and suck up CO2 while releasing much needed oxygen into your aquarium. Natural waste and byproducts from your shrimp may be harmless in small doses, but if you are breeding and have numerous shrimp in a tank, an abundance of nitrates can stress and possibly kill your shrimp. Moss balls act as filters that suck up debris and toxins such as nitrates, nitrites, ammonia and phosphates EASY TO CARE FOR WITH MINIMAL MAINTENANCE --- Just as appropriate for starting out with your very first shrimp tank, as they are for an expert with multiple shrimp breeding aquariums, these low maintenance aquatic plants take up little of your time and even less energy. The only requirements to care for the amazingly resilient Luffy Nano Shrimp Balls are room temperature water, indirect sunlight, occasional water changes and a gentle squeeze every now and then. LONG LASTING NATURAL CHARM --- Naturally smaller in size, the organically beautiful Nano Marimo Moss Balls have a long life and remain small in size for many years to come. Growing at a very slow rate of only 5 mm (0.2) each year, these exquisite aquatic plants have an impressive lifespan of over 100 years when taken care of properly. Along with adding charm and beauty to your shrimp tank, your pet shrimp will have live companionship throughout its entire lifetime.
