Hi and welcome!

Cover the two sides of the tank also and try and keep your humidity up around 70-80 %. If you can keep your temp up around 78, it should raise their metabolism and they should get hungry.

They are just adjusting.

I would remove the moss and cover the rocks with Eco earth or plantation soil, unless you plan to always bowl feed.

Keep things really quiet where they are.

They are pretty! I have 3 myself .

Keep us posted and good luck!
