what is it??

thanks for your help... :D

but now i have to go eat dinner, so will be slow on replies if you reply again..
 
well i've found something else...

last night after everyone had gone to bed, fish tank lights off, etc, i went out to get a drink and had a look to see if there was any movement..

Theres something, its about 10cm long about as skinny as a piece of spaghetti and swims like a sea snake or something (only thing i could think to compare it with) oh and its white..


Any ideas???
 
no idea what dorsoventrally means but it went side to side, just had its head up near the top of the water.. and im not sure about the sides of it.. it kinda looked smooth but then the sides of it looked as though it had ripples...

there are 1000's of worms that u can just get hitchhiking and millions in one area in the ocean...if u can catch it then try if not u shouldnt need to worry. i have un ID'ed worms in my tank that swim around at night and they have caused no harm. and dorsoventrally means um...i cant really enplane it other ways....i guess top to bottom....but not really. sorry about the scientific term...and a bio major i tend to turn them out...if i ever confuse u in the future feel free to pm me about the term:)
 
haha fair enough.. well he hasnt caused any harm yet, and im happy to have the extra life in there, makes it more like the ocean i guess, all the little critters..

If he starts causing trouble then i will see about doing something about it.. shouldnt be hard to catch, cos he sits at the top and moves quite slow...


Thanks for your help..
 
answering your first question about your caterpillar looking thing.
I do believe you have a bristle worm. I have a couple in my live rock and they haven't been a bother to my tank. I do believe one of the reasons they show up is from over feeding and they will multiply so try feeding less. I cut down on my feeding and don't see them anymore. But don't worry cause they won't harm your tank

usually the deposit feeding bristle worms dont swim...their larva stage will but typically they stay on the bottom when mature.
