Blue tuxedo urchin, missing, presumed dead?

[mikestanked]

This is what I found today, after about 3 days back from a 2 day vacation. It was found behind my LR, maybe it got stuck and couldn't get out?

How long have you had it? Those urchins can be notoriously sensitive(as I found out myself). Likely died of stress or lack of food. They're supposed to eat corraline and stuff like nori, but can be difficult to get eating.

I had it for 5 months and it went through the ringer.I Just found it odd that it was hollowed out in a matter of 3 days??

What kind of clean up crew do you have?? If it died and you,have a good crew, they could have eaten it in 3 days. It depends. I have personally never had a urchin die on me.

Maybe 4 red legged hermit crabs, 5 Margarita snails, cleaner shrimp, 3 peppermint shrimp,chocolate chip starfish?

 

[Cjsanders757]

If I recall starfish eat sea urchins?

 

[Rosesrblu1]

Live aquaria doesn't mention they eat urchins specifically, but they do eat other inverts. If the urchin died, the starfish and the shrimp could have polished him off in 3 days. Also, choc chip stars need a deep sand bed and large tank.

My chocolate chips did fine without a dsb

My ccsf has done well also without a dsb, he mostly eats my Coraline algae

U thinking of a sand shifting star?

Kio, live aquaria doesn't say they eat urchins. They do say they eat coral, tube, worms, sponges, clams. I have 2 sand sifting stars, and they aren't predatory to other inverts.

OP... However,I did a bit more digging and another website. Fresh marine, does say they eat urchins. I would say your star is the culprit.

I have always wanted one, because they are very beautiful, but the cons for me outweigh the pros with this species

Was speaking on the DSB part. Never heard a CCS needed one.

I had a ccsf he ate my urchin ate a couple hermit crabs and murdered a nem ccsf I have no love for them

 

[Hocky puck]

And to answer your question no check your lvls he prolly turned to a soup when the star couldn't eat all of him. You could have gotten a spike with rhat

Yeah my NO3 is high and my black clown goby is acting strange( not swimming, or going after food much) so I cleaned my glass and did a 15% water change yesterday. Soooo basically anybody want a ccsf, j/k but I do plan on getting rid of him once I switch to reef mode, probably around early next year. I was just tripped out that he was sucked out that fast, I don't know the anatomy of an urchin so I was surprised
