They are tricky Lil buggers. Just some advice, if they find a spot and u disturb them, they will usually fine a new one. Lump, my brown, always finds a way to dissapear on me. I'd need a dentist mirror on a flexible intena to find him. And I have kermit, that's green all day then brown at night, and lump who's brown all day and green at night. Like ying and yang. Have fun, but try to let them settle, even if u think they escaped!
