Hi everyone I was interested in getting myself a yellow boxfish......BUT... I read that if it gets scared it will let off a poison that will kill everything in the tank including itself. Now I dont know anyone that has ever had one of these, so im unsure if can keep it or not. I have a lionfish in my tank, but he is a little baby, small. So my question is, how jittery are these fish? in terms of how easily is this fish frightened? As im really not going to be happy if everything in my tank dies!
