Staurocladia oahuensis

[paullondon]

The Cladonematidae family decided to show up in my aquarium. I cannot tell exactly if this is Staurocladia oahuensis or Staurocladia bilateralis by this quality of the movie, but anyways, it's interesting to observe them and hopefully they will disappear before doing any damage to my aquarium...
I would be glad to hear your opinion and experience with this little guys in your salt water tank. https://youtu.be/UZ_xhYKTH7s

 

[Calappidae]

I've seen them on the side of my glass before. They just made a sudden disappearence a few months after the setup.

The only information I can find on distinguishing the two was this document.
