Diagnosis on Java Moss

[Bradders]

Hi All,

Most of you know my setup, but I included some details just in case below my signature, including lighting and dosing.

I added some Java moss on coconut to the aquarium approximately two weeks ago, which was all green when received. There seems to be growth, but it is leggy and brown, as per the picture below.

I wondered if this was telling me something, and if so, what advice you might give at this stage?

Thanks,
Brad

Those are moss sporophytes. It's a normal part of the moss lifecycle and it's making spores. I would do nothing.

Thanks @ElleDee - I will do nothing!

What happens after this spore stage? i.e. do they need a trim at some point or do that change etc?

(Sorry for questions - still learning a lot with plants).

Hi all,
Absolutely fine, as @ElleDee says. In fact it looks really healthy.

I added some Java moss on coconut

It doesn't matter at all, in terms of it role in the tank , but that probably isn't Java Moss (<"Taxiphyllum barbieri">) and the reason is......

It's a normal part of the moss lifecycle and it's making spores. I would do nothing.

Java moss very rarely produces spores <"Vesicularia dubyana - Java moss">. The good news is that the <"shape of the spore capsule"> is one of the taxonomic feature that allow scientists to get an ID.

Thanks also, @dw1305 - as you have educated me in the previous posts, if it's healthy, it's all good!!

I am bedazzled why they sell it as Java Moss - when in effect it is not?!

The sporophytes are ephemeral and will die away on their own I believe.

Yes, they just fall off.

Moss naming is a real mine-field, unfortunately people just call them what they like and then apportion a fairly random "scientific name" to them.

In some cases we know that a moss is sold <"under the wrong name">, but in most cases, when you buy a moss, it is <"pick a name">.
