Egor continues to hide but has himself positioned where he can observe what is going on in the livingroom. He seems to come out more when Spongebob is on. He is eating at least one fiddlercrab a day. Whenever I tap on the tank he comes to the front of his cave to see who is there. I have noticed, when my sons try to observe him, he flashes more colors than when I am there. Tells me he does know the difference in faces. He is O. Briareus, so I need to think about a larger tank at some point. Gimpy is still holed up in her cave. When you shine a light under the rock you can see her eye. She took a crab about a week ago, killed it and then make a point of coming out to put it far from her den. Only time she has come out in a month.
