I am considering getting a BTA for my 29 gal cube, mostly so my clownfish will leave my poor tube worms alone (he tries to host in them). I currently have a mixed reef including sps, lps, a crocea clam, and a couple rock flower nems. So.... I know that BTA's wander until they find a home they like. I also know they can divide. What I don't know is how often they become a nightmare that dominates the tank. Assuming it has sps-quality lighting and flow, how often do these guys just take over? Do they tend to sit tight and not divide if they aren't stressed? Is this just too small a tank to even consider one?
