Hi all,

I recently finished reading this journal, which looks into the Dietary intake of a selected population of Golden Mantella (Mantella aurantiaca) individuals. It is a few years old now (2007) but anyway, interesting read!

Abstract:- We studied the diet of a population of free-ranging Mantella aurantiaca, an alkaloid-containing poison frog from Madagascar. As in other poison frogs, this species is thought to sequester alkaloids from arthropod prey. Among prey, mites and ants are known to regularly contain alkaloids and mites appear to be a major source of dietary alkaloids in poison frogs. We predicted that mites and ants would constitute the most important prey item for these frogs. Prey inventories were obtained during the rainy season by stomach flushing 23 adult male and 42 adult female frogs from one population. Males had smaller body sizes than females and ate smaller prey items, but males and females displayed no differences in the number of prey items consumed. The numerical proportion of ants in most specimens was surprisingly low (11% in males and 15% in females), while mites were slightly more frequent (34% in males and 18% in females). Other prey items consumed in large proportions were flies and collembolans. Comparing the total of 5492 arthropod prey items with 1867 arthropods sampled from the frogs’ leaf litter habitat, the proportion of prey classes did not significantly differ among the samples, indicating a low degree of prey electivity in this population. Our data suggest that not all poison frogs exhibit a continuous and active preference for feeding on ants and mites, but instead some may consume high proportions of ants due to a high abundance of ants in their environment.

Hope you enjoy it, provides some good insight I think!!

    Does anyone know if aquacare general tonic is ok for axolotls as a treatment for bacterial or fungal infection?

    Hi Lilith, you can check the medications page for a list of axolotl safe treatments. Although if the infection is mild, I would stick with fridge and salt baths!

    I believe the fridge gets to about 54°, so if you can replicate that in the tank, it might be okay. I personally would fridge just to make catching them easier, and if the infection is something in the water column at all, it will hopefully die out while they're AWOL (I'm thinking like ich for fish, not sure if axies have an equivalent)

    My three inch axolotl was having trouble pooping up to a few days ago. I wasn't feeding her as often because I was scared I would just add to her constipation. I fridged her until she pooped (twice), and then began to feed her around 6 bloodworms every other day. she's been pooping everyday now, but she's at that age where you can see through her stomach and I always see poop ready to come out but has not yet passed. I don't think she's constipated anymore, but I'm not sure and i don't want to over or underfeed her... any advice?

    Oh ok thanks! I thought she might be ready for something more. do you have any advice about the apparent poop problem?

    @Lilith, fridging is not required for fungus treatment. Read my thread on treatment.

    Its probably not pooping because its hardly beign fed, it pooped in the fridge because the lower temp caused it to purge itself. If it stays constipated you can pm me

    Hi guys. Quick question. I have newly morphed eastern newt efts. They lost their gills but they still prefer the water. I have coconut fiber, moss, hidey holes and some food in the temporary habitat for them (waiting for the other newts to morph as well). But they still run back to the water. Is it the wrong substrate? Do they prefer something other than coconut fiber? I've been doing everything else properly (According to my research) but just wondering why they haven't ventured up. Have any ideas?

    My guess is they simply have no reason to leave. Do they still get enough food in the water? Maybe humidity is too low?

    I spray mist the place every day. And I do still feed him. One of them has finally come out. But now I have another problem. They don't look like eastern newts! I am posting pictures on a thread I've started. If you can, take a look for me and see. :)

    Hi guys. Can someone please tell me the sex of my axolotl. I thought I knew for the past four years but a breeder told me I was wrong. PayPal: Your security code is: 138208. It expires in 10 minutes. Don't share this code with anyone.
