i had bought a valentini puffer almost a week ago. from day one he started picking at my serpant starfish. but today i noticed he started picking on my coral banded shrimp. i don't know what that puffer did to that shrimp but man she is still pissed, she chased th puffer clear across the tank ,and wipped it good!!LOL.. but i thought ok this is insane the puff. is picking and the star. so i desided to take the puffer back to my LFS and exchange it for something else..so i had gotten a purple hawkfish..but the shrimp is still mad as heck. and wanting to fight anything that comes near it...but i hope it calms down soon..i think it will when it realizes nobody else in the tank is out to get it...
