Exclamation My Java Moss is growing something weird

My java moss hasn't been growing so well. I bought it from an aquarium enthusiast 2 months ago and his was growing great. He told be that he has to clip the moss every other week to keep it from dominating the rest of the tank.

I did my research and tied it just the way the websites and forums said but it's not growing. The only sign of growth was a small portion attached itself to a rock.

Today I noticed that most of the stems are brown, light in color, and translucent. I don't know why it's not growing. I have a 15 watt bulb on all day. The only other plant in the tank is Wisteria and that is thriving.

MOST IMPORTANTLY, I noticed that there are fine pink "hairs" growing on the tips. I don't know what they are. There is a link at the bottom with someone else who had this problem but was never resolved. It has images similar to my tank.

I vaguely studied mosses in school and I know that some terrestrial mosses reproduce via spores. Does Java moss reproduce like that? I can't find any information on the web about it. Please help.

My guess is you are giving it too much light. Aquarium plants need about 8hrs of light. What kind of light buld are you using?

Hummm, that pink stuff is kind of pretty. I also have java moss, and it lives but doesn't grow much by any means. I'd love to know what to do to make it grow too. How large is your tank?

probably lack of nutrients and CO2, but what kind of light do you have?

Interesting. These flowers resemble a plant in my garden, but I cannot remember the name; not that this is related.

Mosses do not flower, so say all botanists. I did some digging and can't find any reference to this, except for the site where I assume you got the photo, as I found a second, but no info from anyone there. Very helpful place.

I have asked about this on a couple of my plant groups, and will report back what I find out.

Do you have any salt in the water? My plants started dieing off until I realized I was treating ICK with salt . Water changes and everything went back to normal. Java moss is very tolerant of low light but does do better with more. Mine is doing great with 50 watts of CF (6500K) on my 20h and around 65w of T5HO on my 40 breeder. Less light means slower growth. I would try brighter light in the daylight range.

I am using a florescent 65 watt bulb I think. That's all I had lying around. I can't find any information on this. I think it's strange how Java Moss is the most distributed type of moss in the hobby yet not a lot of people know too much about it. Just basic information.

I have a heater in my tank now. At first when the moss was introduced I had a cold water tank to achieve lobed shaped leaves on my Wisteria. I've added a heater a few weeks back that regulates the water to about 78 degrees Fahrenheit.

I don't add any fertilizer because I have a few fish and shrimp in the tank. Most of the nutrients come from the fish poop and food that they don't consume.

That would be great because along with my yucked up plants, my moss has that stuff too. I pulled a ton of it out of there tihnking it was just more algae of some type that was affecting the moss.

My colleagues have advised that these "stems" are moss anchors, sort of like roots, that the plant sends out to anchor itself to wood and rock. It is trying to "attach" itself to the water, in a sense. If these are trimmed off, it will spread other ways. The "pink" is not a flower, as we already knew (mosses do not flower), though it does look like one I admit.

I am also told that these are more likely to appear if the moss is not trimmed and not fertilized. Which probably explains why I have never seen any on my moss, which is covering all the wood in some of my tanks, but I fertilize weekly.

Back to other points earlier in this thread, mosses prefer subdued light and shade and often will not do well in direct or bright light. They do best in soft water which will have more dissolved CO2; in hard water they will manage if sufficient CO2 is present. Mosses are one group of plants that cannot use bicarbonates as a source of carbon, only CO2.

Weird. My java moss grows and grows.... and grows. The only time it browns is when my platys and guppeis want a salad.
