  1. Today
  2. Well I wish you luck in separating them, hope both species do well in your care!
  3. Then I will try to sort out my mix to two pure colonies. The seller told me it might contain nymphs of surinamensis so I have to start sorting. Will keep the mixed colony for feeder purpose.
  4. Yup, P.nigra are black and have red legs, and in my experience are a little longer than P.surinamensis.
  5. Then I will try to sort them out. Nigra is all black? Then I probably have most of them right now, no brown adults here 😁 /Henke
  6. The Surinams breed and grow faster, P.nigra in my experience take almost twice as long as the P.surinamensis to grow, so I think the Surinams would take over your enclosure, given time.
  7. Why do they out-compete the P. nigra? If they have plenty of food and everything they should get the same ammount of food, water, hiding places etc or is the P. surinamensis faster?
  8. Exactly, and I assume the Surinams will eventually out-compete the P.nigra in the mixed colony over time, so it's likely that culture will eventually become all P.surinamensis, given time. Surinams apparently have an affinity to end up in other cages, I keep mine pretty secure so that has not happened with me, but I've heard of other keepers who had theirs get into other roach enclosures, and even isopod and millipede enclosures too.
  9. So if I keep them as a feeder roach this doesn't really matter and I can create a "clean" colony by taking the black with red legs to a separate container later then? Not sure why they are mixed, probably because they need the exact same care and are same size etc but I'm a little bit picky of clean colonies some times so I will try to create two separate colonies later. My hissers are mainly for my own pleasure but these little girls will serve as a food for my T:s but also for my own viewing pleasure. They are in peat at the moment so it's a little bit hard to see them all the time if you don't put your hands in and disturb them. /Henke
  10. Yesterday
  11. They can't crossbreed, no, and it should be easy to tell them apart when they mature, as the adult P.nigra will be black and the P.surinamensis will be brown.
  12. I don't use anything for my roaches at the moment. -For my roaches I use sterilite gasket boxes. I drilled small holes in the lid with the tiniest drill bit available all across the lid. (Small enough so the babies can not get out.) I then inserted an air pump hose (for fish tanks) by drilling one hole in center of lid large enough to put the hose through. The lid stays sealed and locked at all times. (unless changing/feeding them). There is enough fresh air circulating in the tub from the air pump, and enough holes to allow stale air out. I also found it keeps the humidity at a good level also. I sometimes will use petroleum jelly (Haven't in a while, due to no real need for it with the gasket box setup.) around the edge/underside of the lid to keep them from crawling up the lid to the holes. The seal keeps them from escaping out the sides. That's my basic set up. Only thing I don't care for with petroleum jelly is it melts and make a awful mess. It can be hard to clean up at times.
  13. My new colony of P. nigra is not pure P. nigra, it contains alot of P. surinamensis. How do I tell them apart? Does it matter that I have a mixed colony? They don't cross breed since they don't have males, right? /Henke
  14. I normally have the opposite problem just way to many males...interesting it can be so different colony to colony
  15. I know 3 possible methods , - vaseline oil 3-4 on top of box - silicone oil - idem alcool+ talcum powder....you mix the 2 , you put on top of the box and you wait that it will be dry... At this moment, only 2 ssp are able to travel these barriers: hemithyrsocera vittata (ex histrio) small nymphs and all size of anallacta methanoides. for this last sp, I try since 3 days with a barrier of olive oil.... It's perfect to stop them but it was just to make a transfer from old box to new box, I don't know how will become this oil when it will become old....
  16. they can cohabitate with snails, but would outcompete shrimp
  17. Second time this year I've ended up with only adult females in my colony and not a male in sight. Any one else have this problem with their Turkistan roaches?
  18. Nice to know that they can't survive and make new roaches I will try the lime and/or PTFE solution, the only thing I risk now is that the hissers sounds to much for my wife to cope with them and that some sensitive guests might find a cockroach on a road trip Maybe my tarantulas can escape at the same time so they can hund in a more natural fashion? /Henke
  19. I use vascoline with any of the climbing species I keep.
  20. Last week
  21. First off, welcome to the forum! I keep my P.nigra in a plastic storage container I got at a Dollar tree, the lid is pretty tight and I've no escapees at all, this species prefers to stay below the substrate anyway. For the G.oblongonata I'd recommend something like this type of container, the lid is completely airtight and escape proof, and my hissers never got out of it. Neither of those species could infest your house BTW, the P.nigra would dry up fast, and the hissers could survive in your home for maybe a week at the most depending on the age of the roach before drying out or starving.
  22. Hi, New to forum, not new to non climing roaches but now I'm going to keep climbers so I need advice Species I will get is P. nigra and G. oblongonata and they will be kept in smartstore classic boxes with vented lids etc. How do you prevent escapes from them and what could happen if they do escape from the box? Someone opened my daughter's tarantula cage so she (the tarantula) took a sight seeing in our house Lucky me my parents didn't visit us during the escape. So I do know bad things can happens but how do I avoid escapes from roaches that climb and how bad can it be if any of these species do escape? Can they create an infestation of my home or will they die off due to low temperatures etc? Even if they climb they will have a hard time finding food they like so there is not much to feed on if an escape will happen. As a barrier right now I will use lime and/or PTFE spray not sure if I have to use booth. One thing is sure, my wife will kill me twice if they do escape /Henke
  23. I wonder if they could cohabitate with species of snails and shrimp?
  24. Thanks, hopefully I'll be able to establish them in culture here in the US, I hear they can be challenging to maintain over multiple generations. Thanks!
  25. They are all beautiful!!
  26. Wow, very awesome!!
  27. Congrats, awesome to see that species has made it stateside!
