  1. Anyone guess what these are?

    Nice, just make sure your frogs aren't depleting their nutrients too quickly by laying that many eggs. I feed my tadpoles fish food and frozen bits of vegetables.
  2. Anyone guess what these are?

    Hi Manders, They are Dendrobates auratus (highland bronze). I keep them in a terrarium together with some of my highland Nepenthes. It seemed like an ideal way to combine hobbies :) Do you have some pictures of your frogs? Here is the father of the eggs sitting on a young eddy And the mother on her favourite bromeliad They don't mind the pitcher plants (or the cold at night). Only interaction I've seen so far is that they steal the occasional prey out of shallow pitchers (like jamban). I've got two more egg clutches developing right now and the first tadpole of those hatched yesterday. I am wondering if the tadpoles would survive in the pitchers but don't want to take the risk of killing them by throwing them in. What are you feeding your tadpoles?
  3. Anyone guess what these are?

    Are you keeping them together with carnivorous plants? I also have poison dart frogs and have made a photo series documenting the egg development of my first batch in detail. The eggs were laid beginning of july and the tadpoles are now developing legs. Sorry to hijack the post manders ;) 2-3 hours after fertilisation, 8-cell stadium: One egg already a bit further in early morula stadium, the cell in the middle is busy dividing 12-13 hours after fertilisation, blastula stadium: 2 days old, early gastrulation: 2,5 days old, gastrulation with yolk plug visible on the underside: 3 days old, end of gastrulation, formation of the primitive streak and primitive node: 4 days old, neurulation with formation of the neural groove: 6 days old, formation of the gills: 7 days old: 10 days old, lots of movement: They hatched at 15 days old
  4. Hello Do you have a picture of the raja?

  5. Fan in mini greenhouse

    Something that also helps against fungus in general is to place a tube containing some thymol crystals in there. When thymol is placed in a saturated environment it kills airborne spores of fungi and slows the growth of fungi by altering the hyphal walls. It also gives a pleasant herbal scent to the environment ;)
  6. Fertiliser choice...

    I use Akerne's Rain Mix for orchids and have found it to be very good both for the plants and for sphagnum. It seems to give the sphagnum a real boost as it really starts to boom after a fertilisation.
  7. Which Sarracenia Flava Variation Do You Have?

    I've got rubricorpora and cuprea, but I can only select one on the poll
  8. Growing H. pulchella epiphytically

    Update: I had to trim back the moss, as it was growing a bit to fast, but so far the heli seems to enjoy it's current placement.
  9. N. Edwardsiana

    I refreshed the page and it now says the same here
  10. N. Edwardsiana

    That's weird, I got mine last fall when it became available again. And if I check the wistuba website it currently says "available after our winter break"
  11. N. Edwardsiana

    If you can grow burbidgeae you should be able to grow edwardsiana. I've noticed that the small nepenthes in my terrarium catch a lot of springtails. The springtails themselves feed on decaying plant matter so they pose no threat, but they do make good snacks for hungry little plants. I've never bothered to cut off the lid to feed them. Mine (still very small) grows in a mixture of sphagnum, perlite and seramis and is doing great so far. edit: I do spray it occasionally with diluted orchid fertilizer
  12. Growing H. pulchella epiphytically

    Dunno if anyone has tried this before, but I recently started growing my young H. pulchella like an epiphyte on the side of another pot. Since then, it has responded with better coloration as its now closer to the light and has started putting out more mature pitchers. The pot is hung into a basket which is lined with live Sphagnum moss which is thriving. Therefore I'm hoping that it will provide enough room for the roots of the pulchella to keep on growing. Anyway, here are a few photographs:

    I have a ventricosa alba that's male

    So what soil should one use for N. villosa and N. inermis? I have both and I'm curious if I could improve on their conditions
