Blue tuxedo urchin

[Junwei]

Does anyone have experience with the tuxedo urchin? In Singapore I am only ever able to find the brown tuxedo urchin instead of the beautiful blue tuxedo urchin.

I bought the urchin to scrape away the hard green algae at the live rock which the snails were never able to get at. To my surprise the urchin was very capable at removing those hard green algae even at rough rock surfaces. It scrapes so hard at the rock surface that what is left is bare white rock. However I noticed it also ate half of my golden clove. I'm worried it will eat my zoas too but so far it leaves them alone even if walking over them.

Anyone have experience with these urchins and are they a threat to soft small corals like zoas?

Just 1. My tank is 25 gallons. I have a very small urchin and it is like scraping every part of the rock bare. Except nooks and cranny where it can't get into. It's always eating away.

Yup, agree 1 is enough for 25g. Tuxedo Urchin is very hard working.

But 1 thing about this blue tuxedo sea urchin...they will tend to move your corals, when it is bz working...

Have one for over 2 years.  Ime, One is enough in a tank.  Will only eat unhealthy n dying cloves or zoas. Other than that, a good reef tank mate.

i have 2 in my tank, they do run over my zoas and cloves but they dont eat them. they will however move pieces of  coral frags if they are not secured.

The most 1 for a 25g. I have a 50g and 2 seems to be quite a bit already
