Black Spiny Urchin

[fredfish]

It's probably reef safe. No it will not stab everything, just those things that are foolish enough to bug it - like a sloppy aquarist who keeps banging his arm against its spines ;)

It may or may not eat coraline. There are more than one species of black spined urchins. I had one that never touched my coraline.

I say had because it starved in my 65 g tank. :(

I won't be keeping any more urchins until I get a much bigger tank.
