    Default Pipa carvalhoi breeding

    Hi everyone

    I'm new here and as you will notice, I'm not fluent in English. I'm sorry for occasional mistakes.

    I have two adult couples of Pipa carvalhoi and after some hard work, I could make they breed.

    The sad part is I couldn't keep the tadpoles for more than a week. In my opinion, the water conditions is OK, the temperature is OK, but they don't feed.

    I already breed Xenopus laevis several times (albino and normal) and used to keep the tadpoles with crushed fish food and newly hatched brine shrimp, but I think this is not working for Pipa carvalhoi tadpoles.

    Anyone has some tips that will help me? Or some food recipes that I could try?

    Again... sorry for my English

    Thank you for your attention
    Antonio

    Do you enrich the brine shrimp? You can raise the brine shrimp until they are 48 hours old after hatching. Add a very small amount of spirulina powder to the brine shrimp water. You should see a very light green tint to the water. Be careful when adding the spirulina because too much will suffocate the shrimp.

    Brine shrimp are very low in nutrition, so gutloading them will increase their values.

    I never tried to enrich the brine shrimp.
    When they hatch I use them in one or two days.
    I'll try this time

    Thank you!

    Thank you Terry

    I downloaded this paper on researchgate.net

    I noticed that my females carrying eggs has the same appetite that the males and the females without eggs... very interesting... and they show the same results in this paper...

    thank you

    Glad you were able to use the article. I have experience with Pipa pipa and Pipa parva. They are great frogs! God luck with breeding your frogs.

    Thank you Terry

    Have you ever breed your Pipa parva?
    What kind of food do you usually offers to the tadpoles?

    Thanks

    Hi,

    the best food for Xenopus and Pipa parva tadpoles is pure powdered spirulina without any additives (blue-green algae) for all tadpole development. You do not have to use another food as fish flakes and similar. You give small amount spirulina on water surface. The spirulina will slowly sink and disperses into water column. I recommand you to use gentle aeration to slow down spirulina settling on the bottom. I do not clean or make water change for all tadpole development (Xenopus) or once a day I scrape bare bottom (settled spirulina and feces) and than I suck it by hose and change 1/3-1/2 water volume (Pipa). You must use only as much food, the tadpoles are able to eat it during a few hours and water is again clean, than you can add again another food. Overfeeding is dangerous, because spirulina decomposes and tadpoles will stop to eat and are very nervous (fast swimming). It is good to keep tadpoles in relatively small water volume. The reason is the tadpoles have to filter all aquarium water volume in a few hours. At the start I use approximately 0,1 litre per tadpole and at the end of development 0,5 litre per tadpoles (no less!).

    Hi Daudin

    Thank you so much for your recommendations.
    I started this thread about Pipa carvalhoi breeding in 2016 and since then I have made little progress. I suppose my biggest chalenge is related to the fact that my 4 adults (2 males and 2 females) are brothers and sisters. So, consanguinity could be a problem here in my case, originating weak tadpoles.

    Anyway, when spring comes here, I'll try to breed it again and I'll post the news here.

    Thank you.

    Hi Antonio,

    I do not think the problem is your animals are siblings. In Xenopus or Hymenochirus people keep and breed siblings again and again for many generations without serious consequences. Amphibians are not sensitive to breed siglings (compared to mammals or birds). I´m sure it will not be the problem at Pipa carvalhoi especially at first F1 generation.

    We can try to keep tadpoles to the metamorphosis together step by step. So, to breed the animals is not problem for you as I understand. Also there is not problem to have young tadpoles.

    Basic questions:

    1. Are tadpoles immediately after the "birth" swimming?

    2. Do tadpoles repeatedly open and close their mouths = they try to ingest food from water?

    Here is my video Pipa parva with young tadpoles:

    https://www.youtube.com/watch?v=zX0W...ature=youtu.be

    The similar behaviour must be at your tadpoles P. carvalhoi.

    Here is my aquarium with tadpoles P. parva for inspiration:

    Name:  P1070445.JPG

    Please prepare:

    - aquarium with pure water (it can be water from parent aquarium)
    - volume 0,1 litre per tadpole
    - bottom without any substrate (bare)
    - moderate aeration
    - temperature approximately 25-28 °C (I thing tadpoles are not senstive to correct temperature)
    - snails and plants are not important in your aquarium for tadpoles (as you can see it on my photo)

    Please buy pure 100% spirulina powder (it is not necessarily to be product for fish, but also for people as nutrient supplement).


    So I´m not able to get this beautiful frogs here in Europe. Maby I can breed it through you :-)



    It would be good to send some photos of your aquarium(s) or animals.

    Thank you.

    Hi Daudin
    Thank you so much for the information above.

    I used to keep my tadpoles almost like this... but I keep in less water. I'll change next time.

    I'm going to move to another city this week, so you can imagine that I'm in a rush.

    I'll send some pictures for you as soon as possible..

    I'm sure that with your help we will be able to breed this species successfully.

    Thank you
