Urchin in 12 gallon?

[saltman123]

I saw some super small sized urchins and was wondering if they are ideal in a 12 gallon tank? I keep zoanthids, ricordea, and many other soft corals. Pencil Urchin and Pin Cushion Urchins are what I am considering.


Think super small urchins will do ok in such a small tank?

They will eat your coralline algae.

They will also grab hold of anything that is not secured down and drag it around the tank like it's their job. However that may not be a problem for you.

Guess i'm NOT getting an urchin. I want to keep any coraline I have, and my tank is teeny and the hermits already do their job of moving stuff.

Maybe one day when I have a bigger tank.
