Tomorrow they will arrive at my aquaristic shop. I hope the water parameter will not be too strange ..
If the EC is rather high – that would be because of Natrium chloride, I guess, for disinfection?It would be first rate help, Dorothee, if you could get hold of quite some pairs. I have informed Bernd, but he replied from Tennessee that somebody else should save some pairs (for Chester Zoo and others). We surely will distribute them in Hamburg, but we surely have not enough offspring presently in comparison with the need.
If you are unsure, please write to me privately.
Hello Pawel,
I have measured my water – no ammonium inside. I use peat granules very rarely and when my store is empty, I will not buy peat again. I use your recipe for black water.Perhaps I should in a few words explain why ornaticauda is in focus here.
It is one of the three species with a very special courtship behaviour; head up. The others are parvulus and (most striking) sumatranus, which even stands upright more than 90%.
But this is not the main point. P. sumatranus (regularly) and often P. parvulus are easier to be bred as P. ornaticauda. Even very experienced breeders have from time to time problems with breeding ornaticauda. Sometimes, it works as if there would be no problem at all. But then the series stops. And it seems to be nearly impossible to get offspring.
It is this strange irregularity that is most annoying with this attractive species. Are there simpy “good pairs” and “bad pairs” or what else is the clue to this problem? In most other P.-species we do not have such irregularities than here with ornaticauda. Up to the present day we do not succeed with establishing a sound, growing stock. On the other hand, the species is obviously present in nature with good numbers. From time to time they are exported in huge numbers.
This is the task: to solve the riddle of its irregularity in breeding success in captivity. Therefore we must try to find the explanation.
—— Bad news: no P. ornaticauda in Freiburg arrived – Ruinemans cancelled shipping because the fish are ill and they have to take care for them before delivering.
And if they ever recover – they would have to be ordered anew – with a new minimum quantity order of the shop ——-
Perhaps someone from the P.P. should contact Ruinemans directly and get ornaticauda directly from them if they recover?
Sad news, even worse is that if they recover, we are still going to be in vain about the damage caused by the illness and may be by the treatment too.
if they recover I would still give it a try. On the other hand I doubt that any wholesaler would treat the fish the right way, they are most likely kept in tap water and without adjusting the environment to their needs I do not think they have much of a chance. I have no idea why people in trade always try to harden such kind of fish and I have the same experience with South American species too. traders put them 8° DGH water, pH 7-8 and than wonder why they are dying. RO for those couple of tanks with these fish would cost them close to nothing and only a little effort. Of course I do not mean to offend anyone in Ruinemans if they are different. I know from my own experience, that from the epidemiological point of view it is very hard to limit all the transition vectors but I beleave that species from very acid black waters are very well protected by simulating their environment well.
I think that Ruinemans is different; they know what they get and sell. For many wholesalers fish are fish and selling fish is like selling tomatoes or software. But when Ruinemans got licorice gouramies they knew that these are blackwater fish living in very soft, acid waters.
Although it is bad news that the fish are ill, it is good news that they did not ship them because of that. In most cases it’s Oodinium and very, very often traded Paros are infected by that. But it’s not seen by the people and often it’s not even seen by the aquarist who buys them. The cause is very often to be found in Asia already. Whereas European wholesalers as Ruinemans know well about the differences and try to act accordingly, the Asian weeks after the catch are often a martyrium for the fish. It begins with the catchers who earn cents only and often combine one small catch and others in the same bag, removing the dead every second day. Then at the exporters station, there are generally no Paro-specialists working, and many other species are their bread-and-butter-fish.
When the small but fine Mannheim-shop “Rasbora aquaristics” still existed, Mme. Hanel mostly received Paros in the condition of illness by Oodinium. And she treated them with heat and salt before selling any of them further. My first P. ornaticauda had such a history, but afterwards they were sound and without any illness. I am not sure it is the same this time, but I do think it a good sign that Ruinemans realized and tries to combat it. However, we can only hope they will recover.

Thank you very much Peter, I hope it is the case with Oodinium. As Andrzej posted expected end of treatment, it also leads me to think they are dealing with some parasitic infection. I am glad that Ruinemans are different and I wish there were more different competent companies.
The fish put up for sale.
Unter Wasser has ordered and today they arrived … now 20 ornaticauda are getting used to my water … The pH of Ruinemans water was o.k.: 5,9, mine is 5,5. But EC was 2000, mine 33. Now at 1500 …
The fish look healthy and in a good mood as far I can assess it …
So some of them will go to Hamburg on Tuesday if Bernd is still interested 😉
