Check the listing for details. Sinking Java Moss Balls Live Aquarium Paludarium Plant Decoration. Condition: New. Listed at 8.99 USD. Nano Sinking Java Moss Balls, ~2mm (7/8 in) diameter. - Perfect for any sized aquarium, paludarium, fish bowl, or jar that will hold water! - Made from aquarium-grown, exceptionally healthy Java moss wrapped around a bio-ball to provide the highest level of surface area for beneficial bacteria. As this is a live plant, there may be some brown parts as shown in the pictures. This is completely normal and is not a cause for concern. - Java moss is exceptionally hardy and will survive in nearly all freshwater aquarium and lighting parameters making it a wonderful beginner plant and an easy introduction to keeping live aquatic plants. - This Java moss is suitable for all species of freshwater fish. Fish and invertebrates that nibble on plants, and bottom-dwelling fish particularly enjoy this plant. - Though the tanks that my moss is grown in contain no snails or other pests, there are snails, shrimp, and scuds in nearby tanks therefore I can not guarantee them pest free with 100% certainty. If you are worried about this I would recommend a bleach or H202 dip. - Photos are very close to what you will receive however they are not the exact moss balls and are meant to be a representation only. All plants will vary slightly in appearance. - Orders may be briefly delayed if the weather is too extreme. If you have questions or concerns please get in touch with me and I will do my best to assist in any way I can. - Standard shipping is USPS First-Class Mail. It is highly recommended to upgrade to USPS Priority Mail at checkout if you have the funds. I don't make anything off of it and your plants will thank you!
