Hello! I started 4 months ago with 2 hermies; Cookie and Dorothy. They were in a 10g aquarium. I got a 30g about 7 days ago and 5 more hermies. I already had the experience of my first molt! Dorothy molted about 2 weeks ago and is doing great. Cookie has been under for 5 days. The other hermies are still in the ISO. My questions might sound silly :idunno: here it goes, for the new tank, I would like to have a bubble pool. Everybody talks about it, but I dont know exactly what to BUY AND HOW TO SET IT UP. Second questions, my hermies are medium size, all of them. How deep should the pool be? Should it be a bubble salt water or a bubble fresh water? All my hermies are Purple pinchers, I think. I use a mix of sand, salt water, and cocohusk for substrate. Thanks for your answers, I've learn so much from all the past posts, I wish I have found you back in September when I got my first 2 hermies.
