Do dual crowns normally have two mouths? When I originally got "Barry"
he had dual crowns but only one mouth.....



If the tube is hard, its a coco worm, if not its not a hard tube coco
worm, Hard tubed worms are coco, soft tubes are not.m

Barry is definitely a hard tube.....I occassionally have to give him a
nudge when he decides that the best location is on top of one of the
corals I have on the substrate....

Not saying the
"baby" is not a product, of big barry,

A question that will never get answered because it didn't survive the
button polyp die off....it was right next to big "Barry"....I also have
smaller FDs that came in as hitchhikers on the LR....and by the position
in the tank it was unlikely it was one of them....but as I said it is
academic because it got killed off....


Tube worms send out eggs for propagation........What I would say you
have is a typical small tube worm that happens to be next to a larger
type worm who is now sporting a new mature crown since its a double
crown....

The smaller one died or at least moved on to pastures new in the tank -
who knows if it went to the back of the tank behind the rock....It is
the large worm who has the double crown and two mouths - maybe the
growing of an additional mouth is typical with a double crown - don't
know which is why I am asking....
