So, I went to Petco and I was only supposed to get a new tank for Jekyll. Yeah. Two tanks, several new ornaments and a plakat later... Meet Sherlock. He's a HM double tail. He's been there a few weeks. I almost bought him instead of Merlin the last time we were there. I swore I wasn't going to get anymore fish, but...he was still there! So I figured, what the heck? What's one more?
