possible tank mate?

[rc]

ive heard that you can keep certain urchins and britle stars with octo, can you keep sand sifting stars with them also? (without them eating them)

 

[Rockthis11]

yup sand sifting stars will work. Octos dont eat echinoderms

 

[Colin]

But avoid big jaggy urchins like pin cushions as they always jag the octopus

I wouldn't recommend a pencil urchin, either - nice urchin in the right place, but mine has eaten a lot of my coralline algae and doesn't really help much with the tank clean-up. He's pretty, though, and doesn't bother the octopus (except that sometimes the urchin's path leads into the octopus's den!).
