Have a few hitchhikers that I am trying to ID from my TBS live rock. I’ve been dealing w. plenty of good and bad hitchikers (30+ cirolanids on 8lb of LR thus far), but here are a few more I’ve yet to confirm ID.
1) Think it could be a dorvilleidae worm but seems rather long Has been quite active during the day picking stuff of sand/rock. Have not seen it completely out of the rock and it’s very quick at the first sign of movement. Thought it was a cool video to share!
2) These white/translucent tubes are growing quite rapidly. Assuming they’re a form of tube sponge. Have them all over several rocks. The red sponge on this rock is starting to “transform” into a tube as well.
3) misc coral. Tiny and not in a great spot, so hard to get good pictures. Added a few pictures under white & blue light.
4) Yellow worm I saw last night. Believe it may have been an oenone worm, unfortunately. I actually had it in my turkey baster and it escaped before I removed it from tank. No where to be found now.
5) Same rock as above, but pointing out this weird mucus / film that seems to only appear at night around the holes of this rock. That’s what made me believe it was an oenone worm as I know they can produce such a thing to capture prey, however, I’m not sure if it appears like this. Any ideas?
ALSO, the black and white speckled creature in the top hole… maybe a leopard polyclad flatworm? Seems rather small. Have at least one other in a hole on a different rock. Never seen them leave the hole.
6) Not going to try sharing the one horrible picture I have as you cannot make it out, but there was also a nudibranch I saw last night… looked rather similar to a berghia (maybe it’s wishful thinking, to help w the apaista hitchhiker), but instead of straight “spines” they were rather curly. It was completely whitish color and maybe 1/2”- 3/4”. Anyone aware of a nudibranch that looks similar to a berghia? Will see if I can locate it for a better picture tonight, but the first time I saw it was last night.
Thanks!
