At work I have a little 15 gallon tank that is admittedly a bit of a 'beater' tank. It's got a 150W MH bulb a CPR BakPak skimmer, no topoff, a little heater and a single Seio powerhead. It's barebottom and I don't dose. I do keep the glass clean and every so often change the water, but other than that this tank doesn't get a lot of fuss. One thing that I have noticed is that this tank produces RBTAs like nobody's business. I started out with a single anemone a year ago and now I am up to 11! They are all very healthy, sticky and a beautiful red color. It's like a red flower rock garden. I believe the reason they split so much is because of my water topoff strategy (or lack thereof). I'm pretty lazy when it comes to topping off, so the water level frequently drops pretty low in the tank. (i.e.: 2 inches below the rim) When I finally decide to go to the drinking water station to fill up my jug, I always just dump the full jug into the tank directly. I believe that the resulting salinity shock induces the RBTAs to divide. These RBTAs are clones of the original RBTA that I bought from an RC member years ago. Between the ones that I've sold and across all my tanks I've probably produced 30 or so anems.
