    P.S.: I find the C.p.parvidentata here at private breeders and at aquaristic shops. Perhaps they are kept as living food too for different fish.

    I think we should forget all traders fantasy names! We should use the scientific names, and this kind of shrimp is named Caridina pareparensis parvidentata.
    And I don’t think, they live with our Paros.
    They hadn’t been mentioned here in the Projekt, I found Informations in the german Aquaristic Magazine “Amazonas” July/August 2014. They were described as being as far too reproductive for normal tanks.
    So I decided to try them. They were described as being very good in getting used to different water conditions. They seem to be a very invasive species, means that no other shrimps have the opportunity to survive as a species in their territory.

    And I am very sure that they already managed to reproduce themselves in my tank because I see more of them than in the beginning and I see very small ones and very big ones. Of course not as reproductive as in normal tanks with tap water.

    And the truth about this we also will know some time next year , because the life time of shrimps is very limited. If I am wrong, they will disappear some day next year. But for now I claim, they do reproduce, although other experts claim it not being possible!

    This happens in my Linkei adult tank with following parameter: EC about 30, pH 4,8 – 5,8. Many plants and Java moss to hide, leaves on the ground, moulding materials, also elder cones.

    I am sure, if the Paros have the chance to catch shrimp babies, they will eat them.

    Some time ago I tried with Caridina simonis about which we already talked here in the thread “The shrimp question”. They didn’t manage to survive. But I never had the feeling they had reproduced themselves.

    P.S. indeed seems that nobody has tried till now to bring with them shrimps from the habitats of our Paros.
    And I had been told at the Hamburg meeting that someone who tried, got thrown them away by the custom officers at the airport because they thought, that would be shrimps to eat for humans …

    Hi Bill,
    do you think about catfish for having something like a cleaning team in the tank?
    I think it is already clear that we don’t speak about breeding tanks, but about the tank for our adult offspring.

    In two of my tanks of those kind (for my P. linkei) I have now since quite some time caridina parvidentata. This species is known for being very reproductive and being very tolerant to the water conditions.

    I have learned that they seem to need some time to acclimate themselves but then they even reproduce themselves in tanks with 5 pH and EC of about 30.

    I think they can be useful to clean the rests of brine shrimps not eaten by the Paros and to be living food themselves when still young.

    Dear companions,
    I think there is a missunderstanding. The Aqua medic is an osmosis plant:

    Liebe Freunde, ich glaube hier findet ein Missverständnis statt. Die Aqua Medic … von der Ghia spricht, ist eine Osmose Anlage ….

    Hi, A.J.,
    Perhaps you should be more patient until you get the right stuff? Not taking vinegar but wait till the elder cones arrive? B)

    in reply to: My sp ‘sentang’ journal #8871

    I assume you feed living, fresh bred arthemia? And the “spoon” is just an example for your measurement???? (I can’t imagine to feed living arthemia with spoons … that would only be possible with dried, dead anthemia …)

    in reply to: My sp ‘sentang’ journal #8869

    Hi A.J.,
    perhaps I overread it, but I can’t find any informations about what you feed your Paros beside microworms at the moment. Arthemia? Or dried food?
    Or do you have many plants in the tank, which don’t like sour water and which are dissolving themselves?
    There must be something in the tank which causes these many degradation products.

    in reply to: Living food for Paros #8849

    An update: my three different sieves work very well. And now I have found out, that in the JBL Konus down in the lower end, are collecting (after stopping the air pump) about 25ml eggs. If you let pour them out in an extra little glass, the rest is very clean new naupliae, just on the top stay the rests of the eggs. So it is nearly perfect…

    in reply to: Water change #8848

    According to the fact, that our tanks are a lot of different to a natural slow floating river, I decided again to give the tanks some air, ether by little bubble stones or by oxidants.
    As well I experiment with shrimps in my group tanks (not in the breeding tanks) to keep the tank more clean. At the moment I have two tanks with caridina parvidentata and in my tank with Sphaerichtys selatanensis I have a group of very resistant Red Fire.

    I make 50% water change once a week.

    Hi A.J.!
    You write that the only filtration shall be some plants? Perhaps it would be good to include at least a small inside filter?

    That sounds interesting, Rafael!

    in reply to: Bacteria Tests in Paro tanks #8794

    Thank you for the tipp, Peter! With googeling I didn’t find anything else than my kit above.
    To Thomas: my kit didn’t show any trace of fungus.

    in reply to: Bacteria Tests in Paro tanks #8778

    I have payed 7,76 Euro for each .. the real name is: Stricker Dip Slide Combi Bacteria Test Water Bed (Combi because the back side has a fungi test).
    If you search in the internet for the product, you will find it on a big american internet trading platform … ;-).
    If you can get it anywhere else more cheap, I don’t know…

    in reply to: Culturing daphnia/moina? #8772

    Oh … at the moment I have given up Moina …. My last try was a disaster … The first time I had them, they where o.k. But they are rather precarious….
    At the moment I have a try with caridina parvidentata in the “society tank”. They are said to be very fruitful. But not for breeding tanks, because they shall be also very keen in hiding … At the moment I see nothing of them. After a while I will take out the Java moss in that tank to see …
