"I love these! I struggled with attaching Java moss before. It would turn brown and make a mess. But this is still green a few weeks later and seems to be in place well. Thanks!" -Amanda O. Via Etsy Just plop in your tank, and you'll have a mess of anchored Java moss(Vesicularia dubyana) in no time! These are drifting, low light, and easy care plants. I love them in mine as they are great at sheltering fry and baby shrimplets, plus they do some serious heavy-lifting at biological filtration! This order is for one clump of Java Moss, securely attached to a Lava rock for stability and anchoring. These will vary in their natural states, but will be about the size of a ping-pong ball, 2" up to three inches. SUBMERGED-GROWN Growing requirements: 65-80 Degrees Fahrenheit Ph 6-8 Low light intensity. Medium Fast growth speed Co2 not needed Java moss is a super plant all around. It requires very little in the way of light, temperature, or ferts. You will notice faster growth in a higher- maintenance aquarium, of course, but it isn't necessary. This is an excellent starter plant for freshwater aquariums. My mosses love their community tanks, with minimal fertilizer and average light/ room temperatures. I do have snails in tanks, but no duckweed! If you'd absolutely rather not have snail hitchhikers, definitely look up how to do a bleach dip. You'll receive yours burrito- wrapped and heat sealed in a plastic baggie to retain moisture and oxygen. Thank you for looking, aqua friends!
