Haven't measured it in a while to be honest, but it's over 15 centimeters, because that was his length for more than a year ago. It's still growing of course, but it is bigger than an avarage P. waltl already. This is my favourite species. They're big and beautiful. Raising them will be hell though, because they aren't much easier than L.laoensis. I've got 50 eggs and the female continues to decorate the Eleodea with them.
First larvae have hatched yesterday. I will try to raise some in pond water that has gone through a coffee filter, but most will be raised in tap water with an air pump like I did in the past with L. laoensis and the Paramesotriton sp, which Schultschik called the red warty newt. In the Netherlands we don't need to treat tap water (except for a couple of areas), because there's hardly any chemicals in it.
Trying to use filtered pond water, because I want to try raising the larvae less sterile. I will even try to feed them Dapnia, though Paramesotriton seems to be sensible to Saprolegnia sp. Don't like sterile setups, because when something goes wrong, it goes wrong big time. "Dirty" setups have a better "buffer", or so I've been told.
