they ARE like, the cutest little things... get this, I have TWO, much by accident..
I got this first one, and named him "Schneider", since he went strait to work being a handyman like that guy on "One Day At A Time"
Well, after his first night watching him dig a hole in the front of my tank under a featherduster... I never saw him again! I thought "Jeez... he hasn't even come out to EAT... and it's been over a week.. I guess he musta been a good snack for the hermits"
So I ordered another one..
So then, I was feeding my tank, LITERALLY waiting, AS THE FED EX TRUCK was IN ROUTE TO MY HOUSE FOR MY DELIVERY... and the little twerp pops up at me from behind a rockl! So I snapped this pic after I was done squealing and cursing him:

LOL, LITTLE B@S-TURD!!

lol
So my new one came an hour later, I named it "Mrs. Romano" (To keep with the 70s sitcom tribute I had going on at this point)...
and I haven't seen her since... but I KNOW she's in there, 'cos I aint gonna fall for THAT again...
and I hadn't seen either of them until today, when Schneider popped his little buggery self up out at me
Ummm... ok, this reply went nowhere, I dunno what to do about QTing them... mine's got himself such a cave under that rock, I dunno how I'd get him OUT (or Mrs. Romano, if I could find her).. let ALONE what to do about a barebottomed tank...
Maybe put some small shells & larger ones in a "pile" so they can at least feel "hidden"?
