I introduced a 12" snowflake eel to my established tank about four months ago, feeding him frozen krill and frozen squid cubes daily, making sure he was always fed he was living in perfect harmony with everyone until after four months later it gets up and eats both my Scarlet Skunk Cleaner Shrimp in one day! I don't understand why he would just get up and decide he wants to wolf them down? Keeping an eye on him now to see if he decides to go after any more live stock...not sure if to replace my poor shrimp at $20 bucks a pop.
