I lost one of my fish yesterday! I came home from being away for the weekend to find my yellow lab dead inside the mouth of my dragon! he loved to swim in any tight spot he could find so i removed anything he coukd get in. But i left the dragon that blows bubbles because my eel lives in it. I never thought he would fit in it. Seems he swam in one end and couldnt get past the part that releases the bubbles. I wasnt home to help him. i feel awful! So i know this isnt a question like i should be posting. Its more a warning to people to learn from my mistake .
