The Puffer Forum

I am a newbie, I should have given you the full scope. I have a 30 gallon SW tank that has been up and running for 4 months. 30lb's LR 2" Crushed Coral Substrate No fish reside in the tank, I however have a sea urchin & conch. I would like to make the "blue spot toby" my only fish...

I was wondering if a blue spot puffer will eat/kill my sea urchin & conch?

Thank you for the advice in advance.
