Java moss care info Care: easy Co2: no Growth rate: slow Placement: tied or attached to a surface Lighting requirements: easy/low light Color: green/brown Max size: always expanding Propagation: cutting/pulling apart Please note: Moss often times has some brown strands mixed in, this is normal it will grow in and look very nice but understand it needs time to grow in and establish. You MUST attach it to something, if you just toss it in your tank it will go everywhere like confetti, so it must be tied, glued, or attached to something so it can stay in place and have a chance to anchor in place :-)
