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.
Try various foods to mimic a natural diet. If your worms are dead, try living things for sure. My newts prefer live food almost exclusively. My eastern newts eat snails, black worms, baby brine and others. They are like picky children. Maybe blood worms are their broccoli lol
Hey there guys! My tank is cycled but I'm still battling ammonia spikes just when I get it down to zero. I keep the tank clean and do water changes when needed to lower it. Ammonia is about .25-.5 right now, 0 nitrite, 20 nitrate ppm. Not sure why two months in now it's still fluctuating?
@axolotl nerd, rads, the cycle has crashed or the tank wasnt fully cycled to start with. Remove the animals to a seperate tank or tub, give 100% daily water changes. It can take a while to cycle a tank if its yr first time.
Hey guys! We had our first unexpected hot day and I was an idiot and forgot to put on the fan for my axolotl tank. When I came to feed her at around 7, I noticed the tank was 75 degrees!! It has never been this warm, it’s always a stable 67ish without a fan. It was only this warm for today (yesterday it was normal temps), and I immeditately got the fan on when I saw. It is down to 69 degrees now. Is my axie going to be ok with the increase in temperature for a day?
