Hi Everyone - I've been a lurker here since January - always reading and keeping up but never posting. So Hi! My boyfriend and I have a bimac. We've had him since Jan 10th and he's doing very well and getting big. He ever comes out for my boyfriend but he loves me. He's out for me all the time. He plays in front of me and likes to do tricks and dance. But last night he was out and I was looking at him and I went to get a little closer (like I always do) and he inked! For the very first time ever! I'm not quite sure why either. I didn't make any sudden moves or threaten him. My question is why did he ink? And I've heard it's bad if they ink? Any thoughts on this to ease my mind? Thanks! P.S. the water looks perfectly clear as I think the filters and protein skimmer took care of everything. Should I still do a water change?
