[quote=”Little” post=3057]Helene —
No we have no such term for that. Perhaps that’s because we never have hobbyist that would have tanks in those conditions ;)[/quote]👿
(But – as far as I have heard – it can work very well)By the way – you may still call me Stefanie ….. 😉
[quote=”Little” post=3055]”Altwasserbecken” – The English word you are looking for is perhaps “aged” ???[/quote]
Hello, Bill,
yes, “aged” is definitely better than “old” – but I am looking for a translation of the whole word “Altwasserbecken”. It means a tank with aged water which is never changed, but only filled up again. Is there a phrase for it in English?
[quote=”7 Zwerge” post=3051]Hallo!
I’m a bit afraid
of old water tanks…
[/quote]Just to avoid misunderstandings – what Michael and me are talking about are no “old water tanks”! The main difference is essential: the regular water changes! In an “Altwasserbecken” (= German – I don’t know if there’s an English word for it – translated literally it’s “old water tank”) you don’t make any water changes, just fill up the evaporated water from time to time. A tank running without filter but with consequent and regular water changes can never be called “Altwasserbecken”!
Hello, Dorothee,
I can only agree with Michael.
I have not one single tank which has more technical equipment than lighting. I have tank volumes of 12 liter, 16 liter, 25 and 27 liter, 54 liter and 120 liter – and none with filters, pumps, heating …………….
As Michael says – it’s only a question of water changes (I change about 25 to 30% each week; more disciplined in the smaller tanks than in the bigger ones) and feeding.
I only feed live food – even to the fish which would also take dried food – as most of my fish only consume live food it makes no difference to me.
And I can only recommend to put some shrimp into each tank …….. the best cleaning team I’ve ever seen. Caridina simoni lives and reproduces even in the kind of water that paros prefer.My rubrimontis are the most aggressive fry I’ve ever seen. Not even the fry of my Badis fight whenever they meet – the rubrimontis do, being not even 1 cm long. And the tank is not overcrowded – there are never more than 4 young I see together, and of different sizes. And it’s not only the bigger ones which attack the smaller – no, the smallest are no better. And also it’s not the short encounter I watch in my quindecim fry, e.g., – no, the menacing goes over minutes.
Every time you look into the tank you see two siblings eye to eye:
Sorry – enlarging the fry means enlarging the mud ……….
[quote=”Peter Finke” post=3039] Has anybody asked the breeders (Thorsten and Anne) already?[/quote]
Should I ask them for their opinion? Or whether there might be something wrong in the lineage of the nagyi-pair (possible parents of this young) I bought from them?
I think the last can be excluded – as far as I know these nagyi from Pekan Nenas all descend from those that Martin Hallman imported a few years ago.But I’ll send them an eMail, anyway – they should indeed have a look on this fish.
[quote=”helene” post=3037]At the moment I think there a really big ‘gap’ between the inner and outer band of spots/bands in the tail. If you look at your profile picture of your other nagyi, it certainly is broader.
But then again, perhaps we are not considering that even a small nagyi male has got to develop, – maybe it doesnt come with perfect grown up patterns right away, but develop these as it grows. [/quote]That’s definitely right, Helene. And watching this it seems to me that the development of colouration follows no strict chronological order – which I find astounding. As far as I know, e.g. from ornithology, the development of (feather) colouration normally follows a strict chronological order. So strict that an age determination according to (plumage) colouration is possible in many species.
My “real” nagyi-male (the possible father of the one in question) developed the iridiscent bands in dorsal and anal fin from the beginning, simultaneously. But it took this male unusually long (according to expert statements) to develop the tail fin colouration.Look here, that’s another picture of the old male (being still young):
The bands in dorsal and anal clearly visible – but the pattern of the tail fin still just a hue.
However, my “questionable” young male never shows the “normal” striped body colours, so it’s not easy to compare it to the older one in it’s younger days. As far as I remember I have never seen it in the plain brown-and-yellow paro colours – it has always shown this marked reddish colouration, even when showing stripes.
By now, it’s colouration at least remains extraordinary.
New photos from today – I think he’s developing into a normal nagyi-male – one with a stronger red tone than usual, but nevertheless a nagyi:
Two new pictures from today – after again having not seen him for a few days.
To me – definitely a male, and I also think that nagyi-features become more visible – although I still find the colours extraordinary.
It’s creeping underneath the leaves very often and chasing brine shrimp – so here it’s only an aspect of the anal and caudal fin:
I just recalled – this fish has been unusually red from the beginning. When I first saw him he was about 1 cm max., and I was not sure if it really was a paro – the fry of my quindecim and rubrimontis never showed this reddish colouration:
Compared to my other fry a quite extraordinary colouration.
Got some more pictures today. To me – still looking “nagyish” from first impression – but the closer you look the stranger the colours you detect:
Watch the purple proximal base of the dorsal fin resp. the bluish proximal base of the anal fin along the belly, which becomes red near the caudal end of the fin:
Against the light – strange colouration of the dorsal fin – even for a young fish with no fully developed colouration. Note the purplish base.
The white spot near fin ray no 10 is no artefact, it can be seen from far(not sharp, but just to give an impression, also see first picture of this post):
The caudal fin is almost framed by a strong white seam – even at the vertical hind rim of the fin. I’ve never seen this feature in my “true” nagyi male.
[quote=”Peter Finke” post=3015]Not the tail only, the other fins are not typical nagyi too.
And the photo of the “nagyi”-male when it was young is strange, too. I would not recognize it as nagyi.
Never seen something like this.
Why do you think it to be a nagyi?
Have there ever been adult nagyi and quindecim swimming in the same tank?[/quote]Hello, Peter,
the young nagyi male (bred by Thorsten Kolb and Anne Pähler) indeed looked a bit strange in it’s youth – first showing really no tail fin colouration. But it developed to a “normal” nagyi, as you can see in my avatar picture and in my nagyi thread.
I first supposed the young fish to be an offspring of my nagyi pair – the “Yeti”-story I reported some time ago. But finding it looking so strange now when showing first colours it reminded me of my quindecim – and I suspected it might be an offspring of the accident I reported here some time ago (see the beginning of this thread): When my quindecim female somehow got into the tank with the females of unknown species which I bought from an import last year. And I – trying to put it back to it’s husband – mistakenly put one of the unknown females in the quindecim tank instead – where it mated once with the quindecim male before I succeeded in putting it back again in it’s own tank and in re-uniting the quindecim pair.
So – if it’s an offspring of my nagyi it should be nagyi,too 😉 .
But if it’s not it must be a hybrid between quindecim and ? And I think I see nagyi features – the short, rounded ventrals, the reddish-brown body colours. You once supposed my unknown females might possibly be nagyi – that’s why I think it might have a nagyi mother – if it’s a hybrid.
