sipunculida worm? pretty neat, he ws scurrying around my sand bed, got knabed by my toby when i put him back, hope he will pull through

 

Here is the usually worm ID link:

Worm Hitch Hikers

Images are too far away for me.

Grabbing live stock, no that can not be good.

 

yea thats where i went first, im almost sure its a peanut worm. fancy that a creature we know little about in my own aquarium, how cool!

 

Yeah that looks about right. I used to have one of the white and black stripped variety, he was smaller and did not go after fish.

 

the majority seem to be detrivor eaters, nice. a little +1 to my cuc.

 

I think he was saying the toby grabbed the worm when he returned it?

 

he gave it a bite when i put it back
