Ouch.
Weird that must be one sticky BTA. In all the years I've had BTA (pretty much since I started in the hobby in the 90's) I've had BTA's but they've never posed a threat to anything alive since they're just not sticky or aggressive. Carpets and LTAs I could see taking down a fish .. BTA's .. in fact with my RBTA, I pretty much have to jamb a krill into its mouth otherwise the krill floats away after a minute or two.
