So the other day we bought some new live rock for the gf saltwater tank and I, being the saltwater idiot i am, asked if we could get a puffer fish. well little did I know that they are not the nicest of fish and they are also not reef safe. so we put him in the tank and he instantly starts biting everything in sight along with some of the smaller fish so we had to throw him in to 'jail' a nano salt tank that luckly has nothing in it atm.
