They definitely go exploring but almost never beyond the rim of the tank. A few months back (I either wrote about it in this journal or started a thread in the inverts forum, can't recall at the moment.... maybe both) I discovered that they love to leave this tank and go exploring during major barometric pressure shifts. Other than those moments, they've never gone quite this far.
Haha, yes, tickled to say the least.
Most of them end up as Crusty McCrustersons by the time they reach the bottom of the tank and go exploring on the stand. This is a first.
I have no idea what the deal is but mine come outta the tank when there's a major weather front rolling through. Took me forever to figure it out and I still don't understand it entirely/haven't had enough time to truly observe.
Not sure what it means, other than it just seems to be typical behavior for them. I guess I don't notice in my tanks with rims because they all have covers and I just don't see it.
On another note: One of my oldest PFR females (at the moment) just died. 599 days old - almost made it to the 600 mark. She only had two clutches and lived about half her life with some molt-related deformities. Quite a record for this blood line.
