[Cdime712]

Do you have high nitrates? Urchins hate high nitrates.

Nope zero! All of my water parameters are good

The only issues I had was my calcium was raised very high! Right now it all good

Has he moved at all? Turn the lights off and see if he starts moving.

Any spines littering the sand?

Turn him over. If there is a big hole where his beak should be, he is dead.

Looks like he still has some suckers out in the first image, would guess alive but perhaps not doing so well. As another member mentioned, spines littering the sand ?

Didn't see any spines littering.

He still looks alive to me

I have lost a few urchins, unfortunately- the first sign I saw was the spines falling off. The urchin will look comparatively smooth over the surface- if you've ever seen a sea urchin shell you'll know what to look for. Once lights are out, you should see tube feet (They look like translucent worms hanging off the surface of the urchin- that's how they move around. The bottom of the urchin will look like a hole the size of a dime or larger (depending on the size of the urchin). Best of luck!

Green things I believe are tube feet, and the red pentagon I highlighted is the mouth/butt- that is the size of the hole you would see, if I'm not mistaken.

Do you have much food for him?

Also, zero nutrients is bad. Corals and algae will starve. You need above-zero nitrates and phosphates, especially phosphates, at all times.

I know I'm supposed to know this by now but what do they eat?

Question is are they supposed to look like this?

 

[NeonRabbit221B]

That is one sick looking urchin. Can he move on his own? Just watch him... Try feeding Nori

May be a little stressed but as long as you still see the tube feet you should be good- once spines start dropping that's usually a sign it's on the way out.

 

[bsr2430]

I have personally never seen the tube feet up close, would love to see him in action.

What’s the update? He moving around?
