Cannabilism in S. salamandra terrestris larvae

Any tips on how to avoid this apart from giving loads of live tubifex etc or raising in individual pots? i found previously with ambystoma opacum that separating was essential but thought less of an issue with S.Salamandra species? but already the odd limb seems to be going from new larva . So have separated for now and experiences welcome.

My salamandra larvae were not very cannibalistic at all. I had 20 larvae and I only lost one or two, and that wasn't to canibalism. So, I wouldn't worry about them eating each other or biting arms/legs of etc.
I also found that larvae would go straight onto dead food as they already have their back legs/sense of smell. So things like frozen bloodworm/tubifex and chopped earthworm worked very well. Of course, live whiteworms, small earthworms, live bloodworms and tubifex work great as food too, so if these are a viable option then I would certainly suggest using them.

Hope this helped. :happy:

In my experience, cannibalism will always be an issue of varying significance (limbs lost and juveniles eaten etc) and occurrence (how often) which can be reduced or prevented (if they are reared independently which isn't always possible given the limitation of resources etc). To reduce the likelihood of cannibalism, I try using a variety of strategies together.

I reduce the density of youngsters in a tank as much as I can. I provide plenty of food (live food such as the larger species of daphnia and tubifex and also chopped worms (the pieces are large enough to display muscular movement. I don't like leaving chunks of uneaten dead food in the water as it degrades water quality. Also crushed cricket innards and the frozen foods obtainable from aquarists such as blood worm. I tend to avoid artemia in case of elevated sodium levels, but that's probably unnecessary. In addition, I ensure there is a lot of weed in the water for hiding places etc.

Despite all of this, some larvae grow large very quickly whilst others very slowly creating issues in its self. Some animals appear to be active cannibals and seek out the smaller tank mates whilst ignoring the other food offered. Even well fed individuals have been known to take a bite at a passing sibling.

I have found cannibalism something to be aware of, but not of major concern.

    @Jokerjay, as in water dogs do you mean axolotls? i suggest very heavy research and a fully cycled tank before even considering purchasing one

    Axolotls are amazing until they get sick and then they’re a pain in the backside to treat - I recently lost two axolotls due to unknown causes

    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?
