As Kraken grew, I knew that worms wouldn't provide for his full nutritional needs. I went out and bought him some specialized reptile food in the form of turtle "sticks". I had to break these in half so Kraken could eat them easily. There's a lot of "fish meal" in them and the smell of it drove Rufus nuts. He would grab Kraken by the head and drag him underwater, trying to get the food out of Kraken's mouth. This caused Kraken to become increasingly aggressive when it came feeding time. On more than one occasion he would bite Rufus's lips and ride around the tank attached to him. This also made him more "snappy" about taking food from my fingers.
I took a picture of Kraken attached to my finger during one feeding. You can see Rufus looking on eagerly. More pictures coming tomorrow!
