Acclimatizing a tuxedo urchin

[foreveringlass]

I have not seen my urchin doing that, but I wouldn't doubt it! Mine searches for the strip I put in the sand for my sifting star, because I don't completely bury it. It some how manages to get a small chunk of nori stuck to it. Then slowly works it down to it's mouth. Let me know how yours does with the clip!

I'll try leaving him a strip in the sand, or maybe see if it'll attach to him.

He's been going around the rockwork picking up junk for the last few days. Hopefully he's finding something to eat in his ventures.

So far so good with this urchin. Fingers crossed.

Well bad news.

Last night I noticed he wasn't carrying anything around any more, and overnight he didn't move from the spot where he was. I tried to give him a piece of nori directly, but I think it eventually floated away.

And this morning when I checked, he had lost 80% of his spines and wasn't moving.

What is going on? Water params are all 0. PH 8.4. SG 1.026. Temperature around 80.

Everything else is happy.

Could it be a bad test kit for something?

Sorry to hear about your luck. I don't have a clue what could be wrong. My numbers are similar. Salinity 1.026 Ph 8.3 everything else 0. Sorry I can't be of help!
