I have had my bimac for a little over a week now. I had to do some work on my overflow and he came out to watch me. That is the first time i have seen him come out into the open. We watched each other for a minute. I stood up to get something and he inked and swam off. I stayed between two rocks peering at me for the rest of the night. Is the ink harmful? Do I need to do a water change or will the skimmer deal with it? I hope he comes out more now. Thanks.
