seriously .... tonight i was moving my gonio (rock base was about 2.5"), after lifting it off the sand bed, bristles started scrambling ... grabbed my long tweezers and got all of them. 4 of them 2-2.5" long, and 2 1", and another 3 baby ones (about 1cm). after my first posting here and, including this new catch, I've removed another ~30 .... is this really normal ? seems my tank is a good breeding ground for bristles ! I usually observe them when I turn of the wave, then they strat to come out, really creepy coz a lot ... but i haven't really seen them do any harm .... but still ... sigh ...
