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.
