Ideal water depth for C. ensicauda popei

[snarfing]

Hello all, I am in the process of setting up a tank for some popei newts and I'm finding a lot of conflicting information on the internet at what depth of water they prefer.

Deciding between a 55 gal and a 40 gal tank, the 40 gal has less height but more depth, so i'm thinking their water depth will be the deciding factor

I'm keeping them in a water depth of 25 cm right now, but I've kept them in 15 cm and a lot deeper than 25 cm. All these depths resulted in active animals, breeding and no issues. That also goes for keeping them in water with and without a current. Didn't have problems with both. They don't need a big terrestrial area as well. I hardly see them come out of the water. A little piece of floating cork bark is sufficient. I've kept them below 10 C, but I would suggest keeping them a bit warmer. I've never had problems with warm temperatures during the summer, but I guess they rely on cooler night temperatures during this period. Larvae definitely need warmer temps than 15 C in my experience. Juveniles quickly become more hardy. Most important advice regarding to the enclosure I think is that you should give them enough plants and spots to hide, so they can get out of each others eyesight now and then.
