Axolotls in the new aquarium

I left the aquarium over night and all day today to settle and moved the ornaments and axolotls back into it tonight after work.

Typically all the axolotls are huddled together at one end of the 4ft tank leaving 3 feet empty!! typicl!

I'm not sure about the blue sands but at least I will be able to find the axolotls and their poops really easily!
