George Needs Help!

I'm unsure as to the identity of the stem plant on the right in my 33G. I bought a pot for £1.69 with about 25 stems from Pets at Home, bargain! I found it wonderfully ironic that the majority of plants they had were all delicate, demanding stem plants that require loads of light and CO2 etc. How many Pets at Home customers would have these ideal conditions?

I think it's Rotala sp. ''Nanjenshan'' or Mayaca sellowiana. Any thoughts?

It looks like Rotala sp. ''Nanjenshan'' to me, George.

I think Andy is right.................. its Rotola sp. "Nanjenshan" this is the same plant as Mayaca sellowiana.

Interesting addition George..........

Yep - I agree too It's a lovely little plant and I had some too before my tank was setup as planted - so it all died
Would love to get my hands on some again

This "was" mine - lovely clump !


Edit: actually, on second thought - is it really the same ??
My plant knowledge is limited, but doesn't George's also looks a lot like "Mayaca fluviatilis " ?

My Dennerle manual calls it Mayaca while most other sources Rotala. Tropica say it's actually Rotala but mislabled as Mayaca whilst Plantgeek.net say Mayaca is the scientific name for the Rotala??!!! Confusing.

"Interesting addition(s)?" I'm not too sure whether I like them yet, I'll post a full tank pic soon in my journal. The stems certainly contribute to the whole triangular effect, especially with the trimming I have done.

Andy and zig - How do you find the Nanjenshan? Growth rate, demands, colouration (I've heard it can go reddish) etc? Do you think it'll be ok with my 2 WPG, bearing in ming my glosso has no probs I'm assuming it'll do fine. Does it have much in the way of root structure i.e. a pain when pruning and re-planting?

BZ2 - My leaves appear more delicate and the stem thinner and different colour - I'm wondering if it the same plant even though in your journal I actually agreed with you that it was Rotala sp. ''Nanjenshan'' - http/www.fishforums.net/index.php?s=&sho...ndpost&p=936079. Very interesting.

How's your 19 going BTW - we haven't seen an update for a while?

Here's a closer shot. Andy and zig, what do you guys reckon, same plant or not?

I dont have any in my tank yet, i think Andy might be minding some for me, i dont think it goes red or reddish maybe more yellowly light brown in high light but i wouldnt consider it a plant for colour (could be wrong) i think it should do fine at 2WPG its a fast grower.

I ordered some of the Fluviatilis from Greenline, and it actaully looks very similar to your close shot - it didn't do well in my tank at all.

I'll do some updates later this week of my tank - thanks for asking

That was my first thought but Dennerle describe the leaves as only 5mm and hair like. Their photo of Mayaca sellowinana looks a lot more like it. The photo of the fluviatilis looks more delicate still.

I'll see if I still somewhere have a pic of what I had in my tank, bought as fluviatilis from Greenline - but yours really does look like it.
I'll do some searching and report back.....

Thanks mate

Looks like Didiplis Diandra to me. The only difference I can see between yours and mine is yours is alive.

I thought of that too but figured Mayaca/Rotala was more commonplace - especially considering where I bought it. Somethig else to consider though so thanks.

Taken from this website, this is what my fluviatilis looked like, and to me looks the same, George (as yours)



This, is really not the best pic either, but here is some of my fluviatilis in the far right corner - I'll see if I can get the full size pic tonight and do some cutting and pasting for a better image.

gf, from the closer pic i'd say it's nanjenshan. It grew really well for me at the start when it was in the open under 1.6 WPG. It's now in a slightly shadier spot and it's still doing fine. It can be a bit of a debris collector but not a major problem.
i haven't noticed any red coloration but my co2 is still a little low so maybe that's a factor?
It doesn't have a major root structure, or it didn't the last time i moved it anyway. I don't think it'll take over your tank or anything like that. Mine seems to have topped out at about 6-7 inches in height so i haven't had any reason to prune it as yet. It continually produces new growth, tiny little versions of itself close to the parent plants.
I wouldn't be able to judge any special demands that it might have but with my sporadic EI it does well.

Zig, it's being well looked after for you, pick it up whenever suits.

I'll try to get a better shot later...

Thanks BZ and Andy.

BZ - I think your original plant was Diplidis diandra judging by some of the photos I've just seen on Google images.

I've just read this, just to add to the confusion!

Contrary to common opinion on the internet, there appears to be a difference between Rotala sp. 'Nanjenshan' and Mayaca sellowiana. The plant pictured below is Rotala sp. 'Nanjenshan', which is the name also used to refer to Mayaca sellowiana by some. Mayaca sellowiana is actually a separate species and can be identified by a finer leaf structure, more golden coloration, and whiter shoot tips under ideal conditions.
