I agree, i started my tank out with all dry rock and put 1 piece of LR in for "seeding". I noticed about a month ago a bristleworm about 10-20cm creeping around early one morning. In the last week i have seen my Blue tang and a Zebra Dart fish both swimming around with bristles sticking out of them.WOW..... I assume some will say great cleanup crew..... I say creepy, and not for my tank.
I know they are good for the tank but wouldn't they need thinning out sometimes, i find they get so big and so many of themI consider them as a great addition to the tank - I am often somewhat dismayed when I see ignorant people (primarily on Facebook pages) claim that all bristle worms must be destroyed by whatever means.
holy cow, every have any of your fish get tagged like i described above?My biggest reached out around 60cm from a rock but with it's tail still hidden :)
On or off they are always burrowing in the sand under rocks. Having said that they are out more now i have lyretails in the DTNo, never. Blue tangs like to hide away in the rocks of a night time so that could be why yours ended up encountering a bristle worm.
What do Dart Fish like to do when the lights are off?
