After "babysitting" the tank in my home office twice while I was out of town on business, I came home the second time to "I couldn't stop looking .. everything changes depending on the time of the day! Can we please get one for the bedroom?" Uhhh.. sure! And now she's talking about wanting a bit larger tank for the family room. Half the time, she'll go with me to oogle at corals. When it comes to fish, she knows what she wants and she's patient enough to wait until one becomes available (in this case, a Dracula Goby w/A. randalii (candy cane pistol shrimp). The budget's not unlimited, but she knows I'm not going to skimp on lights, pumps, etc. either.
She still leaves the maint. and technical to me, but she picks out the corals for her tank. Gotta love it when they get hooked themselves!
