I put a six-line wrasse in my small tank for Bworm control. I still have many of the great big worms, we're talking 4-8 inches, but the smaller worms are now at an acceptable level. They used to come boiling out at feeding time and I've always wondered if the bristle worms didn't wipe out my colonies of spaghetti worms.
I think a six-line wrasse is probably a little friendlier than an Arrow crab.
Reefkeeping is my life; I can't afford a hobby too!
I would like to get a natural predator(reef safe) to lower my bristle worm population. I hear arrow crabs work are these reef safe? what about butterflies are these fish reef safe? anyhow let me know-- iam looking for blue or yellow mushrooms-- I can trade watermelon mushrooms and reds with blue dots-- let me know thanks again H.sosa
Hmmmmm... "big 8 inchers....", Hmmmm... ANYWAY, many of the wrasses that use their teeth to turn over structure (orchids, clown coris, coris, etc) will control BW populations without decimating the total population IF the tank is large enough, anything less than 30 gal (about 3.5 sq feet of bottom) will prolly be devoid of BW if you introduce a predator. Having LR helps, as few fish can move the larger pieces of LR... (heh heh heh)
