Chikan Posted August 10, 2005 Report Share Posted August 10, 2005 Yesterday morning I had a temperature drop in one of my reef tanks due to the failure of a heater. I noticed that the bristleworms in the tank started appearing and seemed to expel fluid like they were either spawning or spewing their guts like sea cucumbers due. I have read that they spawn rapidly in overfeed tanks, pose no threat to other animals and shouldn't worry about them. Just wondering if firstly should I be concerned about a population in the tank and secondly is this behaviour common and was the temp drop like a environmental trigger to spawn etc. An input would be great.

Brianemone Posted August 10, 2005 Report Share Posted August 10, 2005 what sort of temp drop are you talking about?? Quote Link to comment Share on other sites More sharing options...
wasp Posted August 10, 2005 Report Share Posted August 10, 2005 They live in pretty much all tanks, the population will find its own level based on food supply. Quote Link to comment Share on other sites More sharing options...
Chikan Posted August 11, 2005 Author Report Share Posted August 11, 2005 The temp dropped to about 20-21 overnight and witnesssed the behaviour at about 8.00am. I'm just curious what the behaviour was whether they were actually spawning or they were eviscreting like sea cucumbers. I have read that the actual worm poses no threat to fish or invert just the aquarist. Quote Link to comment Share on other sites More sharing options...
Brianemone Posted August 11, 2005 Report Share Posted August 11, 2005 the prickles are annoying (like little splinters) but nothing to worry about i noticed since moving rock into my nano at work that there are alot of little bristle worms cruising around (only a few big ones) Quote Link to comment Share on other sites More sharing options...
petplanet Posted August 13, 2005 Report Share Posted August 13, 2005 I had a big grey worm appear recently in a predator fish free tank. What I could see out of the rock was a good 10cm long, 8mm wide. It was sticking out eating fish food that had landed on the rock while the lights were on. Haven't seen it since and probably never will. My tank at home crawls with worms. Quote Link to comment Share on other sites More sharing options...
