Asking for this Pest tank, think it'll be okay in here? It does contain a Eunice worm,
Still no. Nudis eat very specific things. If it was munching a particular type of zoa, it'll probably just eat those.
It may eat all zoas, in which case, it'll wipe out all of your lovely zoas. Not good, as it'll end starving to death, and you'll have no zoas.
