Hello, Dorothee,
I have the following plants in my tanks: java fern (Microsorum), fountain moss (Fontinalis), water sprite (Ceratopteris thalictroides) and “Süsswassertang” (Lomariopsis, they seem to also use the German word in English). Swimming plants are Salvinia natans, Riccia fluitans and Limnobium.
Limnobium doesn’t like a cover, that’s right. As far as I know many swimming plants do not like to get wet from above – e.g. by condensation.
With Ceratopteris it’s as you’ve been told before in this thread – be patient. It “dies” at first in acidic water – but if you have some “hard pieces of leaves” left, just let them float. They make adventive plants after a while – and these survive!What’s a real success – and nearly not mentioned in context with acidic water – is Lomariopsis. It proliferates even in water with a pH of around 4,5, looks beautiful and provides wonderful hiding places for young fry….
In the middle java fern and some fountain moss, below and on the right is Lomariopsis, and above on the right it’s Riccia:
Lomariopsis again:
Hello, Dorothee,
sorry for the late answer (summer is no forum season for me – the garden claims its rights).
That’s a good question. How are my simoni shrimp now?
They are not “exploding” in reproduction – that’s the same as you observe. But they are doing well, as far as I can see. There are times when I think their number declines. But then again I see many young half grown ones. I don’t know if they really have ups and downs in their population, but I make fluctuating observations…..
Only yesterday I observed some younger ones which measured about 1 cm in my quindecim tank – and some rather big ones, if not to say giants :huh:
My conclusion: They are doing well, but don’t show enormous reproduction rates (maybe they do, but the newly hatched shrimp are eaten by the paros? A welcome side effect).
They obviously moult successfully despite of the lack of water hardness. Maybe they benefit from the fact that the live food I fetch from my garden pond contains many crustacea like daphnia – providing them with all they need to build up their own shells.
One thing is more than obvious and confirms me to go on with keeping Caridina simoni in my paro tanks: The cleaning effect! You can clearly see which tanks contain shrimp and which don’t. This effect – the eradication of organic waste and thus keeping the organic load of the water down – is something I wouldn’t like to go without anymore.I can not contribute to the question of determination – but I agree in the suggestion to wait a little while. I think it can already be seen that there are coloured bands in dorsal and anal fin beginning to develop (especially in the last photo of post 3428), and even the caudal fin (picture in post 3430) shows a hint of another colour band occurring.
Whatever they are – to me they are extremely beautiful, even now while not showing full colouration!
P. nagyi “Pekan nenasi” male and female:
The colouration of the coloured bands of my oldest male is almost golden (depending on mood and age?). More blue or green than this is never seen anymore:
I have the impression that younger males show more blue/green/turquoise – but that might be just my personal impression.
[quote=”ourmanflint” post=3424]Thanks..
The caudal band actually looks orange/white depending on light rather than just white. Glad to have confirmation they are nagyi.[/quote]
Yes, that’s what it looks like in Pekan Nenasi – I only know this form, maybe it’s the same in Kuantan. The white band in the caudal might even show a golden tinge – but it is definitely not blue. Look at the male in my avatar – it’s from Pekan Nenas, and it’s caudal band is yellowish-golden.
Oh, now they definitely look like nagyi!
And as the band in the caudal fin seems to be quite whitish, it might be the form from Pekan Nenas or from Kuantan. That’s just my humble opinion ……….. 🙂
Hi, Davy,
I think Helene is right – it appears to be a form of rubrimontis.
Compare to these pictures of my P. aff. rubrimontis Mimbon 2008:
I discovered a second fry in the “empty” half of the tank today. Definitely aiming to becoming a male:
Hi, Marcin,
yes, that’s another way to do it. But I even want to avoid the stress of separating first the female, then the male. Moreover, in a well grown tank it is not so easy to lift the dividing pane and lower it again without wedging the plants in. Lifting the pane results in an undertow – I prefer to leave the pane were it is and give the fry small holes to slip through. I am sure this will lead to many more surviving fry – when even now, with no visible gaps, some fry succeed in slipping through.
Yes, but that’s just what I want to avoid – I don’t like the thought of catching and disturbing the fry – it’s much easier and free of any stress (for me and the fry!) to let them find their way into safety alone. To me that’s the great advantage of the described idea – to leave the fish without any disturbance and still enable the fry to escape from their hungry parents.
Good morning to everyone!
Some news from my nagyi-pair:
As reported before, I keep my “old” nagyi-pair in a 25 l tank which is divided in two halves by an acrylic glass pane slid in vertically. Like this:
The barrier is not sealed, the pane is only slid in two vertical guide rails glued to the front and back pane of the tank. There still are small slits of max. 3 millimetres, and the two parts of the tank thus share the same water.
As I reported before it’s difficult to get offspring of this pair – eggs or fry appear to be eaten by their own parents. I only got two young “by accident” – I already told about it in the past.
Now I can report my third young of this pair ……….. discovered this morning in the empty half of the tank beside the part which is inhabited by the parent nagyi-pair. That’s him or her:It’s grown this “big” without being fed intentionally. This half of the tank is not inhabited, I don’t put any food in this part, but small food like artemia nauplia is able to cross the borders. As was obviously this fry when being not bigger than some millimetres …….
Hi, Davy,
sorry for the belated answer, but I have been away for a short holiday – and (what always keeps me from logging in here as often as in winter) – there’s so much work to do in the garden …………….
I use gardening peat (as described by Deepin Peat) to prepare the water for the tanks and the weekly water changes. I put about two handful of it into a nylon stocking and hang it in a 10 l watering can filled with rain water. I leave it there for about a week, until the next water change. It works only a few weeks, you have to control the pH from time to time. When the peat is washed out, you have to change it.
I use peat granules only as a thin ground layer in the tanks.
