Thank you all, its really interesting, – 🙂
I could now set up 3 tanks trying out
1. stable temperature (sounds quite interesting, Ted)
2. really careful, intensive feeding of fry from very early
3. a tank with more fokus on humic acidityIts not much of a scientific experiment, but I will try tbem out, – anything that will change. I dont know what to keep doing with these ‘single’ male harveyis, I already have a 60 liter full of them 🙂
So something must be done.
But again, – it still puzzles me why only the harveyis and why all broods, not just once, but more times.
Thank you Stefanie for the links, – I have seen the thread you are mentioning, unfortunately yes, it is impossible for me to really understand.
Martin, – thanks also for answering. Its an interesting theory, –
But also for me its the same conditions in all tanks, – and I have 8 species, only with the harveyies is the problem.And I might breed extensively 🙂 but I feed ‘intensively’ .. meaning I probably way overfeed, – would that not help this problem. Unless its in the very early stages as you say before the fry take any artemia.
I certainly will be aware of it in some way.
Thank you, maybe Martin will see this postings ..
In my case I can say that it is not just in one brood, it is now continually and not just with one pair but it seems with more pair … hmm… however come to think of it, it is actually the same female, – and of course same ‘stock’.
🙂 no, I was also not thinking of starting a serious investigation in a scientific way 🙂 .. but if there was something I could do I would really try.
But its good to hear that I am not the only one that experienced this and maybe I should be happy that I do have at least a few females now and then.But I am a bit curious .. so, its not particular species this happens to ? Its not that p.harveyi is more in risk of this than others ?
It just happens that in my tanks its p.harveyi that has this problem ? or is it often p. harveyi ?
Just wondering ..Then I wonder … were those people who experienced it able to change it ? Did they manage to get more balance I wonder.
I will try something.
The temperature is in between, its definitely not high, no heater involved. Just in a room with room temperature, and this is around 22-24.I have to try to understand this with the humic acid a bit better then. I have not paid more attention to it than in any other tank.
I am not sure how to change this however .. or control it.Good luck with the spawning then, – its really beatiful. I hope it might be possible to find out which species this is, and to keep it somehow.
And a phantastic photo really, – even its an uncertain species, it says so much about what we all are fasinated about with these small fishes.Its really interesting photoes, – but no, I have to admit, I am more certain than ever that this is indeed a dominant female.
The fish does show extraordinary strong and intense colours now, thats quite clear. But in this kind of mood, where it is obvious that the fish is really showing strong colours, it is not showing typical ‘male’ colours. If a male, in this mood, (strongly aroused, strongly agressive or something else) there would be much stronger colours in the bands all fins. Clearly and visible. This fish at this point is showing the optimal for whats possible for it, and that is just not ‘male’- like.
I have seen females become this kind of ‘darkish’ black-ish when in really bad mood, or really fighting with other females.
And even the way the fish fight in some way seems to me to be more ‘female-fight’ than male show off. I have experienced females being really nasty to each other in the way you describe. They can really attack each other. Males .. maybe they do it too, but I think they more show off to each other than actually go after each other..Hi Stefanie, – if you like you are welcome to every now and then have a look into my newly opened flickr account. I just got a very good camera, which of course means I will be taking lots of photoes of my paros. Some, if perfect, I might of course also use here, but at flickr I will put up more. I dont have all species, but at the moment I have eight, – and its so much fun to try to make the ‘perfect’ photo.
Here it is (at the moment theres not a lot of photoes, but it will come, so look in every now and then)
Hello Steff and welcome here, – I can see you are from Belgium – I cannot remember either that there were someone else there, – but you should be close to some connections, either other memebers or shops in Holland ? I am glad to hear you found some fish.
You photoes are nice, I like particular the first,- a very well looking 60 liter I think. But in a 60 liter tank, 🙂 I do think it will be a problem to count the pa
roes, as you say they are excellent hidersThank you for the video, – these are clearly something else than mine.
Do you live in Wellington ? Isnt it difficult to get paroes there ? I sometimes visit Australia and its really not easy there.
Hi Vale. I searched the internet and found some photos and some videoes of ostracods. It sounded like it could be right, however they seem much bigger than the ones I see.
Did you see the video I refered to earlier in this post ?as I mentioned yesterday I have a culture of paramecium – aquired for the purpose of feeding fry. This looks excatly the same as these, so I am not in doubt that it is a similar thing.
🙂 Well, I am no expert 😉 .. but I can always share my own experience as far as it goes. I am certainly not always right in these matters.
But I agree with you that it sounds like a perfect ground and built up, – and well, sometimes it may prove a problem with too much organic material, and too many snails etc, – sometimes it doesnt give any problems.
I use extensively spagnum in all tanks, and leaves, – never any normal gravel. I made an experiment with a tank with lots and lots of oak leaves, actually wanted to make it only leaves, – but it didnt work out, – its clear now theres too much organic material in there, – so theres so many algeas now, – thread algeas… however the ornaticauda’s in there are thriving and breeding .. so … 🙂
If I cleared that tank for all plants and leaves, I am sure I would see those kind of ‘paramecium’ clouds, because its too rich on nutrients I think. And it may not be optimal, but I cant from my experience say that it is very bad either.
