Missing Urchin

It should be ok, but I would do a 20-30% water change just to be on the safe side. If you have hermits, they should help too.

Thanks. Saw him again this morning and he was normal size - strange! Unless, I have a tiny on in there that I didn't know of.

They are amazing at getting into icredibly small spaces, typically when they die they deposit all of their quills and if you have good circulation they should blow around the tank.

Glad he's in good shape!
