Java moss is pretty easy to take care of. Tie clumps to driftwood with fishing line or cotton thread or string until it attaches itself. Any loose moss allowed to float in the tank can become a nuisance if you're not careful. It can tend to attach itself where you don't want it to, and once it's attached, it's very hard to remove it even if you continue to try and pull it off.
hi chatony. i live in UK and bought some Java moss on ebay from seller in Kentucky USA. arrived 5 days later and one of the best moss i have purchased, real healthy and was in sealed moist bag. i tied it down with thread and have done nothing with it since and only has a few hours of light a day. seller grew it in garage with no light and no heater and it kept growing. very hardy moss.
chatony is your moss attached to anything or floating free? Strong water movement tends to move it around the tank if loose and will definately get in the filter. When attached to something and out of a strong flow it seems to do ok.
Welcome! If it's not tied down it will float around your tank and little bits will attach where ever you don't want it It can be wrapped around a small terra cotta pot and it will grow out from that making a java moss cave, or attacked to a piece of wood, or to a flat rock. Imagination is the key here- have fun with it. You can use cotton thread to hold it in place or a rubber band, they will both eventualld weaken from the water and break then you can take the out.
apparently the more you spread it out ' as appose to a clump' the quicker it will grow. I'm still experimenting with mine and bought a nice sized clump of moss recently from ebay and wrapped it loosely around a bamboo stick and tied it down cotton thread. its currently floating next to the filter hose where there is good current and so far the moss is growing well .the moss has 5 hrs of light a day but people do say moss can grow without light. Ive moss on driftwood and its taking longer to grow that on the bamboo stick. one advantage of moss floating on a stick is it keeps the snails away from it. my snails seem to like moss ;D
