In tank 25, a Jack Dempsey lives happily. This fish is roughly the size of 2 large hands placed on top of each other. His name is Bubbles. In this tank I clean the inside using an algae brush and the outside using a rag and vinegar. His usual meal is 10 small pieces of squid, which he eats with ease. I enjoy taking care of this tank because you never know what Bubbles may do, for example on many occasions he has coughed up his food and then eats it again. Taking care of Bubbles keeps me on my toes!
