I am not sure where do You get this 3* info from. Hengeli lives alongside Betta coccina, (0-10dh). Pangio semicincta was found alongside Chocolate gouramies, which live with Parosphromenus in Kalimantan Barat.
I have 8 Paros, 16 Boraras in 70 litres, and it’s not overcrowded. The amount of fish you can safely and comfortably put into the tank depends almost solely on the skill to create hideotus, broken lines of sight etc. 16 is a bit to much, I’d prefer 12, but it’s not that awfull. When they get scared they form a schooling group and they look ok.
Now the question of the water hardeness. From what I’ve read in this forum and the site itself I came to think, that the most important is the 0 KH. The varying pH of several succesful spawnings may point: KH should equal 0, an GH should be as low as it goes. But I doubt that having the GH even up to 8 ( I want it to be around 3-5) is bad. It’s just not ideal for breeding. The leafs falling into the water have some minerals. Than they are eaten by shrimps and/or get dissolved n the water. There is SOME mineral content. Low, but still. These few micro-siemens in the water conductivity are coming from somewhere.
Hi again. I have a question about antoher setup I am going to set up :P.
Don’t kill me after reading the question! Read the whole thing.
My sister wanted me to reorganize the 112litres tank we have. She wanted to have betta splendens, others were for me to decide. After buying the Betta it came to me, that this one is extremely docile. He isn’t even trying to show off before the mirror! So I thought… If I could plant an awful lot of the Cryptocoryne wendtii, cover it with a canopy of several bigger roots, than I might be able to house (not breed, for this I have other tanks) for some time a small group of Paros, at least until thęy reach the puberty and become fertile. What do You make of it?
The idea was to combine:
1+2 Betta splendens
20 Trigonostigma hengeli
6 Pangio semicincta
one Atyopsis moluccensis
and 3-5 Parosphromenus.The tank is 80x35x40 cm. There would be a layer of sand, later enriched with home bred(!) tubifex. About 1/3 Of aquarium would be covered in Cryptocoryne wendtii, a one nice Ceratopteris in the background. A bit of Cryptocoryne retrospiralis, and Hygrophila corymbosa minima. So the bottom layer will be covered pretty well! The floating cover will be created by Salvinia natans.
So what do you make of it?
P. deissneri is suposedly availible in Wrocław. And some other Parosphromenus sp. in Łódź.
Photos of the “deissneri” were promised to me 5 minutes ago by the shop owner. He said, that he will send them in the evening. He seems quite sure of the species.
The other one could be anything, the shop owner is kind of rough, but he also promised me that if he was to make some good quality photos, then he would send them to verify the species.
The spotted dorsal fin might actually point to Parosphromenus sumatranus if they were to develop the filaments.
if it wasn’t the case, then I’d take a blind guess, that this is the species you are looking for:
which is listed as P.allani here: http://www.aquaticquotient.com/forum/showthread.php/85750-Parosphromenus-sp. , but i have literally no idea if this is allani, or not.
It’s in Czech Republic, so I can;t really say.
Aside from that. The shop in Wrocław is able to get Parasphaerichthys lineatus, but it only comes in a bundle of 200. Price of the fish would oscilate around 6-7zł,(about 1,5-2,0 Euros). Anybody interested ?
I found some papers on the daily changes of water temperature in summer in Poland on the example of some rivers and streams. The temperature varies considerably (even over 10 degrees difference).
And of course, first I need to make a controller.
I started digging a bit and got to some interesting info on the monsoon and the climate in Indonesia in general.
I used mainly Polish sites, but nevertheless I’ll give them for refernce:
http://en.wikipedia.org/wiki/Wet_season
http://www.transazja.pl/pl24/dane_klimatyczne/id/Indonesia/Jakarta/temperatura,opady
http://pl.allmetsat.com/klimat/singapur.php?code=48698and info about Thailand for comparison:
http://pl.allmetsat.com/klimat/azja.php?code=48456
http://www.tajlandiaprzewodnik.pl/pogodaWhat stikes me first is the fact, that there os actually only one monsoon season in Indonesia, while Thailand has two precipitation spikes. Since we are interested in Indonesia much more than in Thailand, I will drop the topic of the latter.
What we see next. The avarege temperature of the air is, more or less, constant and equals 27-28 degrees Celcius. But the interesting fact is that the amplitude of temperature varies greatly througout the year, with the smallest amplitude during the wet season in January, (33 max, 22 min), followed by moderate differnces till June, when the difference rises (35 max, 21 min) to reach the biggest difference in October (39 max, 16 min).
As to the rain. Having comparede the differences on the Borneo and in Singapure I can say, that the month with the heaviest rainfall is always January, and the most dry month is the June and/or July.
Here I’d like to state a thesis. Although the primary trigger is most probably the shortage of dissolved material, followed by the stabilisation of temperature and the land getting less sunligh.
I think that it is safe to assume, that water temperature measurments are taken during the daylight, so the recorded temperature is probably the peak temperature or maybe 1 degree Celcius lower. Now here’s the temperature chart for Jakarta:
http://www.panstwaswiata.pl/indonezja/pogoda/
The temperature varies from 3 to 5 degrees between night and day. Now let’s compare it to the annual chart, which in fact shows us, that the difference between avarege max and min temperature equals 4 degrees. This made me think. If it is so with this month, it should be probably the same with others. So I checked some meteograms, and charts, and found notes about weather on Bali in October
The difference is visible. 31 to 23 makes an 8 degree change. Usually, the recomended difference between night and day temperatures are between 2-3 degrees Celcius.
With that in mind I think, that simulating the change could effect in less spawns but of a grater calliber, with more eggs and therefore fishes. I’am not sure of it of course, but I intend to simulate the difference with a heat controller allowing to set day and night temperatures.
I think, that goal would be to make changes during the year: (Day/Night)
24/22 December, January
24/21 February, March
25/20 April, June, July, August
24/21 September, NovemberAccompanied with smaller water changes in summer and more frequent in winter.
The post might be a little chaotic, but the general idea should be visible. Most of my fish are young (about a year or so), so there is some time till the first spawning, but it might be interesting too see if the spawnings would start in the January 2014.
I’ll let You know how the experiment is going.
Ok I understand, but is there an info on how low can it get in case of Paros? Are there any measurments to determine how water temperature changes throughout the year?
In my other topic You said that Paros breeding seson started few weeks ago. Due to what? What was the trigger? Presumably temperature, but how does it change? It drops? It goes up? Artices linked to the site state, that water is cooler, becouse it comes from he ground. Is the temperature somewhat stable? Are there any significant variations daily, annualy?In case of Oodinium, I found some unconfirmed info, that Oodinium is seen in heated aquaria, and is rarely seen in aquaria with the lower temperature.
And last question. Are there any tests to show the productability of the female when bred extensively, in lower temperatures with visible breedeing season, as oposed to the classic and alredy known method?
Sorry for the flood of questions.
Well, now I have:
A pair, that I am 100% sure of. They are inseparable.
An unpaired adult male.
And an unpaired horny female
0:50
Some other videos from this morning (all are dark as hell – the morning light isn’t a strong one).
I will probably be making a joint order for Upper Silesian Aquaristic Association. I might dedicate a 12 litre tank for a pair of anjungensis, and a 45 litre tank for a community of filamentosus.
Pleco.eu also plans to ship Parosphromenus all around the Europe, since they specialize in wild caught plecos, and have enough connections to sell them.
Info I aquired from pleco.eu.
Are you sure you’ll be getting P.filamentosus and P.anjungensis?
-We are not sure.Are these wild?
-We don’t know.How old are they?
-We don’t know.How much will they cost?
-Ca. 1,5-2,0 Euros (6-8 PLN)When will they arrive?
-Airplane should be at Wednesday.Will you post photos after arrival?
-Of course.How many fish will you get?
-We ordered 400 of each.And last one for today. This young male (?) is just insanely adorable and is the bravest of 8 Paros. I got them of course from Martin, they are 1-2 years old, the biggest male is actually the biggest scaredycat of all males in the aquarium.
From my observation, young ones actually enjoy chasing Boraras and like to follow shrimps. Until they turn back and swim in their direction, of course.
Here’s the photo, and beneath you’ll have the link to the full size picture.
Snow is water plus all the nasty stuff in the nearest vicinity.
Plus in order to get a litre of water out of snow you need to use about 5-10 litres of snow.
It’s an idea as bad as it can get.
