Short spine purple urchin.

Then again, my tank is a Biocube with two clowns, lost the goby. I can risk a little more.

What would you be scared of?

I don’t put the LFS water in the tank, I take the urchin fully out of the water and put it in my tank when it’s time.
just curious. i assume its the same method like snails, and crabs
 
Ok now I really am going to start to pray for this thing. It left the seaweed I gave it. Walked over to the bubble algae, and is now eating that...

The whole reason I was at the LFS was to buy crabs for the bubble algae...

What R2R needs is an authoritative review listing the algaes that our tropical reef urchins have a preference
for. (Please let me know if such a list already exists!)
 

Just started another thread… it’s now eating my coral..
