Oh, a divorce, sole custody of my young son, changes in my work schedule, etc etc. If you don't get time to work on these tanks, they can go south pretty quickly on you. That's what happened to mine. Lost all my sps, including that huge monti cap. Glass is grungy. All my softies, RBTA's (I have 4 of them right now), all my LPS, and all my fish are still doing ok. I have some things going on right now and I'm kind of waiting to see what transpires before I decide to keep going and expand, or pack it in and sell everything.
