the pic is actually pretty good , I mean that's what it looks like
I actually did try to feed it but it won't come out any more then that. And YES I did actually try to poke it today!
Funny that you said that , I had a glove on
but all it did was pull back into the rock , it pulls in so far all you can see is rock. As far as I know its never come "out" and yes I check at night too. I even totally rearranged this tank today , and with all the movement "it" never came out.....the mystery continues
