Not nearly as attached as I am to my dog that's for sure =) I am attached to some of my fish. My angelfish is my pride and joy and my whole tank revolves around my lovely Angelica. I also am quite fond of both of my bettas. I love their coloring and the male has a ton of personality and sits on the counter right beside my desk so I see him all the time. My bettas are Gabriel and Gabriella. As far as my platies go, well let's just say I cheer Angelica on whenever I see her gobble up fry and I certainly wouldn't shed a tear if they all went belly up on me and freed up space for something else. If that did happen I'd actually be more worried about Angelica catching whatever killed the indestructible platies. I am not all that cold and heartless, the platies to get well taken care of and I even purchased a secondary tank to help house them. There's just so many of them, and they all look the same, that I can't really get attached or excited about them =/
