They look much more like slugs than worms.
Maybe they are baby sea hares? I have a big black Bali Sea Hare to control
algae.
These little things dont really swim, they kind of float through the water
until they hit something solid---then they inch along like worms. The big
one does the same thing. They do seem to have those "bunny ear" oral
tentacles at the head. These tiny slugs are mustard yellow---the big one is
black.
I dont know how they procreate---I think they lay eggs---But I didnt see any
eggs (not that I`d know what they look like).
Is it possible there were sea hare eggs in the live rock?
any help is appreciated,
stringer........

hi,
I recently noticed what seem to be some small mustard colored nudibranchs
in my aquarium. Are these also considered Flatworms? I saw 1 that was
about an inch long. Then there are about a half dozen others that are 1/4
inch or less.They are kind of cute. I could stand them if their numbers
stay low.
. Are these bad for my tank? If so, what kind of fish would control their
population?
Is it not so much of a coincidence that Ive seen more since I trapped out
the 6-Line Wrasse?
Thanks again-----
Stringer
