Guess we'll have to agree to disagree on this one.
IME Hermits are much more damaging to reef tanks then urchins. My OPINION is that the info on this site is in error.
Just one more quote, this time from animalnetwork,
"Echinoids are probably the echinoderm group that, as a whole, does best in a reef system. Many of them are rather omnivorous and will be good scavengers, as well as eating problem algae. The aquarist should take care not to purchase one of the exceedinglyvenomous species.p Also, many urchins rather blunder around a tank and can be significant ******** decorators. Pencil urchins are nocturnal and almost totally predatory and will eat everything from soft corals to shrimp (Lares and McClintock 1991)."
So obviously pencil urchins are to be avoided in a reef tank.
If you do decide to go with hermits then I agree, it's best to get some snails so they can have something to kill and eat.
Have a good one,
Brent
