Wondering if anyone has been told similar advice about disinfecting live blackworms before you feed them. I had two fish guys share that they soak their blackworms in milk for about 5 minutes and then rinse them in tap water and feed. They told me it is to kill off many parasites that may be inside or outside of the blackworms. Does anyone else have sucsess with this method? Also is their internal parasites are salamanders may host from feeding blackworms?

I wonder if newts in nature have a choice... Of course some blackworms (or the in Europe available Tubifex) is normally found in polluted soils, but I doubt if you can erase for instance toxic things like heavy metals by just giveing them milk baths. Of course flushing them and feeding them something natural so that their intestinse are not filled with dirty mud anymore reduces pollution, but never all.

And I don't think their is need to, unless you feed your animals continously with the same type of food.
I use Tubifex for over 20 years in raising larvae of several newt and salamander species and never had sudden deaths or so, only when I did not wash away the dead worms in between them. And of course I also feed other things like Daphnia and Mosquito larvae (the red ones) but hey..both of these also occur often are caught in polluted water!

Sounds like extra, unnecessary work and a waste of milk...
All blackworms (not to be confused with tubifex) available in North America are farm raised. You may get a few large planaria or a few small leeches in with them. That is about it.

Milk as a disinfectant? I find this so hard to believe.

I would feel safe in betting large sums of money that milk has absolutely no effect on any parasites. In fact, I bet it is less effective than the standard of rinsing the worms off in cold water before serving.

To sterilize black worms you would have to used aged water to rinse them. If water from the sink are use without aging or dechlorination the water, the black worms will die and will not wriggle afterward which doesn't produce a natural instance for the pet your feeding to strike at it. I have tested this out and the chlorine will kill your black worms right away.

This doesn't sterilize the blackworms either.

I've did some google searches and if you trace back the comments on milk and blackworms it seems to have originated with people using milk as a food source and with subsequent posts changing the time to soak and the reason. It looks to be unsupported by any real data (but I only did a short search)....

    i highly recommend “buyanaxolotl.com”- ive purchased from them and received a beautiful animal for relatively cheap, in great condition, and excellent shipping precautions. the breeders are a couple living in georgia (i believe, don’t quite remember) and they’re fantastic. sometimes their website contact page doesn’t work, so i’d probably try just emailing them. good luck and happy hunting!

    Hi all I'm new here I'm just looking some advise on cycle witch is currently driving me insane . So we are week 8 I'm dosing daily with 4pp of amonia and for the last week has been dropping to zero witch I no is good. But my question is my nitrites are sitting at between 0.50 and 1.0 PM and nitrates are between 10 and 20 and neither of these seem to be dropping. I have done 2 40% water changes a few days ago and no change the only thing I can think of is I didnt use the seachem stability stuff which I have now ordered but surely that shouldn't have much difference this far into cycling

  • ytz13513:
    Dropping ammonia with rising nitrate and nitrite is good. It means the nitrifying bacteria is working. You just have to remove the nitrate from the water doing water changes. The level of nitrates is high and the nitrate is also high. The nitrite will be converted to nitrate using the beneficial bacteria and you can add them using quick start or allowing them to naturally grow in the tank. The latter option will take longer. The nitrate can be used by plants, so live plants can decrease the levels, but I would do a water change to get the nitrate at a level that is lower than 5 ppm. 5ppm of nitrate is natural and a good place.

    New here. hope this is the right place to post my question. I had 27 axolotyls aged 2-3 months old. main food has been finely chopped up bloodworms. no problems. I decided to introduce earthworms from my earthworm compost bin for variety. I finely chopped up 4 small earthworms and fed them to the babies. Within an hour 20 of the babies were dead. The remaining 7 (the smaller babies) survived and are now fine on bloodworms. Any ideas why the chopped up earthworms killed many of the babies?
