hey Tim, (thanks for this paper, by the way!). yup, that was surprising about raising the terrestrial eggs underwater. I have seen other species with eggs on the waterline that could go either way, provided sufficient oxygenation of the water (Theloderma, mantellas, some Tylototriton/Echinotriton, hylids, etc.). but woodland salamanders? crazy. I also sent the paper to some Eleutherodactylus guys, some of whom are having trouble with eggs, especially when they remove them. I bet a motivated, technically handy individual such as yourself could make their own automated flow-through egg washers for less than $650...maybe a 'hydroponic'-like system with ebbing and flowing water...
Yeah I was checking out their website, looks like they just use vinyl coated fiberglass screens to set the eggs on, hard to see what the water flow is like from the photos though. Maybe we'll have enough Hemidactylium eggs this spring to do some experimenting.
Welcome to Caudata.org! Looks like the Aark fundraising drive is going pretty well, whichever party initiated, it was a great idea. Thanks for reminding me about that paper...one of the references in it uses LHRH on Gyrinophilus successfully, I may have to try that on one of our display P. ruber with years of retained eggs.
Very interesting article. But I find the use of the term "most" for P.jordani vague. My experience with Ensatina and Aneides is that excessive moisture late in development causes premature hatching and death. Though I'm going to have to ponder the possibility of trying this, at least once.
That was my experience with the D. aeneus eggs too, and I've seen rain trigger hatching in Hemidactylium. However the eggs may reach some sort of osmotic balance early in development and it's the sudden change that triggers hatching. Dunno.
I know I'm getting in here kind of late, but I used to work at a fish hatchery and they used a technique that might prove equally as helpful. They had long acrylic cylinders filled with water and they would run a stream of water up from the bottom of the cylinder. The current would gently roll the eggs to keep them oxygenated and clean. They are pretty easy to make, you could even use a large mason jar. I would think you could use a large, fine air stone in the bottom of the jar to keep the water flowing and keep it well oxygenated. Anyway, thank you posting this paper, I found it very interesting.
hey thank you all so much for your help!! i shouldn't have been so careless, but I love my axie very much and her behaviour has improved as I have started a tank cycle and gotten some good food for her
My axolotls were doing fine until the cycle int heir tank crashed. I currently have them tubbed and they wont stop shedding their slime coat, and my golden albino looks a little red, and his gills dont look too good. Theyre both flaoting and im keeping the tub at 18 degrees celsius and doing 100% water changes everyday, any help on anythingelse? can anyone help?
@AkemiYousei thanks so much. Will do. I have also given them a tea bath before, seems to work their gills are looking so much healthier, my golden albino is swimming around frantically trying to jump out, should i be worried? my wild type is fine
We have an axolotl called Jasper who is approx 3 years old. He was being attacked by his companion so we separated them. He has healed his wounds now but has got very thin. his lips have turned black. he was just looking still and dead at times but ears moved so we knew he was still alive. Hold earthworms right in front of him which after some time he will take you think good he is eating but then it pops straight out again. At the moment he is in the fridge. Not sure what else to do if he can't or won't eat !!
I am new to axolotls myself and one thing I learnt was that earth worms when in distress give off an awful taste - have you tried live river shrimp? Mine really like these and are always happy to 'bite' - I also give them live crickets and pellets which are really pungeant in smell and they always take these - even wait at the glass for them! So sorry to hear he was being attacked by his companion!
