Lies, Lies, Lies!
:help:
These have been the hardest plants for me to grow yet. I buy them and they are lovely. Nice and green and healthy. Six months later in my tanks and they look sick, sad and sorry.

I bought awesome java ferns 6 months ago. They have not gotten even one new leaf in all this time. They are not dying but doing absolutely nothing. They come out of a tank with only stock lights. I have had them under a shop light and also in my planted tank under better lights. Still nothing.

Same with moss. Not dead but not living, either.

My 3 hardest plants so far have been anubias, java fern and java moss. The "easy ones". Everything else needs a haircut every few weeks.

Should I start dosing with iron perhaps?

I could never get java fern to thrive, either. I still have some growing (it attached itself to some ambulia... don't ask), but it's only growing tiny leaves and definitely not doing well. I think it got out-competed by the ambulia nana over the years in my tank (I started with one tiny nana and a couple of large clumps of the fern... now I have more nana than I can shake a stick at... 3 or 4 rhyzomes about a foot long with baby plants coming off them every few inches.. and only a tiny tiny clump of java fern left).

my java moss, on the other hand, grows like crazy and I literally have to pull bucketfulls of it out of the tank so the fishes have room to swim.

I've never had much luck with java moss. I always seam to have fish that liked to pic at it so it would never thrive for too long.

I've had pretty good luck with java fern in the past when using flourish iron and flourish complete plant ferts by seachem.

I wonder if something in your water is either missing or in an abundance. It is interesting you cant grow all 3. If it was only one you say ok, that one is out for me.

I can't speak to java moss, as I've never been able to grow that well either. However, I do have Christmas moss in abaundance, as well as java fern. One thing I noticed is that both like water movement in my tank. Not waterjet type movement ... but visible movement.

I'd almost see if you could set up a simple 10g tank with a java fern / moss and nothing else, and see what happens. Almost sounds like something in your tanks is outcompeting them for a needed and shared nutrient

I have my java fern in my blood parrot tank. There is no other plants in the tank. I also moved my moss to a 10 gallon for my cherry shrimp. My ideas were the same as yours but seems neither helped.

I will get some Flourish Complete as Cliff mentioned and try it altho I have regular Flourish, Leaf Zone and Flourish Iron. I did read just today that Flourish Complete is made for lower light tanks so maybe that will help?

Nothing is dying and everything is green. Just not growing.

Hobbs, are you 100% its not growing?
For a long time I thought mine was not growing, but it was and very very very slowly. I have never had great luck with java fern though, I always get nice plants and end up browning or getting holes.

the first java fern I ever got was not in great shape to begin with, but it was the only one in the store. It was months before it grew at all. On the other hand, I got a different plant a few months after that, and that one spread and propagated to the point that it fills half my tank. I use the same substrate as you and moderate lighting, no ferts or anything else. So, a lot may depend on the quality of the plant you start with.

Java moss is going okay for me except that it keeps getting overrun by hair algae.

I have java moss that seems to be growing under just room light, the tank doesn't even have any lights near it. Java fern seems to grow slowly for me under tank lighting, but seems to do ok. I can probably send you some java moss again in a few weeks if you'd like.

Maybe increase the fertilizer regimen. I have a fair bit of bioload so the fish provide a good chunk of the fertilizer.

As far as Java fern goes, mine is almost a year old and I can honestly say it's not in bad shape but it doesn't look like it's growing anything new. All leaves are green and it's bushy but the root growth is non-existent.
Now my java moss is growing faster than my hair. I have it under LED's in my 55 gallon, under an incandescent in my 10 gallon and without light in my 2.5 gallon. The 2.5 gallon gets 2 hours of sunlight each day. In the 2.5 gallon I placed a cookie sized piece of java moss in it when I quarantined my shrimp and now, a month later, it's a little bigger than a softball. No fert's in the 10 or 2.5 gallon. I do use seachem's flourish in my 55 gallon.

Just for fun after a pruning from my 10 gallon tank, I put the clippings in a mason jar full of tank water and placed it by a window. The jar is full of java moss which is bright green.

As long as it's not dying and is still nice and green, I will be happy. But what is the difference between Flourish Complete and Flourish Comprehensive? I'm thinking that maybe it was the Comprehensive I read is good for lower light tanks but now can't remember.

I try to avoid phosphates because I have enough in my tap water.

Thanks everyone for the comments.

Never mind! I think I'm all mixed up here. Maybe I was thinking of Trace because I think Comprehensive and Compelete is the same darned thing.
