Lol, I'm surprised at how many people keep them though. My mentality right or wrong has changed over time that I don't want fish that can grow to the width of my tank. Heck my only tank atm is 33" wide and I don't think I'd try to keep a dovii as anything aside from a solo wet pet. I'm even more amped about the festae though, I was thinking it would max around14" It should get some good size, my tank is on an autodrip, still gets 1 or 2 water changes a week and they get fed way too much...
