Got Coralline?
Very kind of you to say! I had one with green "lighting" over a year ago so I'm hoping this one sticks around a bit longer. I've also seen them with red "LEDs", which would be wicked cool.
Any special tips to keeping urchins?
Low(er) nitrates, stable water parameters, lots of coralline to feed on and the occasional seaweed snack. I haven't had great success with green or multicolor urchins (just tuxedos and fire) - someone mentioned that green urchins are cold water, which is why they may have trouble adapting to the ~78 F temperature.
Keep us apprised of the growth rate of your fire urchin! The test of mine has doubled or tripled in size since I bought it last year. And forget the mysis: they seem to really, really enjoy chunks of raw supermarket shrimp. And if you have a feather duster, I'd move it now.
Will do. He's an active little guy - having completed almost an entire circuit of the tank. No dusters (someone found it a delicacy).
Wait until you feed it something meaty (with tongs!!!). They quiver with excitement and scuttle over to inspect any dead piece of meat. It's kind of disturbing, actually.
