Yes, you say it looks like a fish, yet he is really a dog! Don't let the fins, scales, swimming in the water, etc confuse you. We got our dog last month at a wedding reception. We started out with a fish, fish bowl and rocks. It turned into a dog, plant, "cave home" and tons of food. This so called "fish" is a finicky eater. We bought the Betta flakes...he would only eat the brine shrimp in it. I bought "baby shrimp", we would eat that sometimes and sometimes not, then I heard about pellets and blood worms, so I bought both of these. He eats the pellets (regular food) and he LOVES the blood worms.
Now to tell you about our dog. His name is Nemo and when I call his name he comes. If I go to the other side of the bowl and call his name he will swim to the other side. He begs for his food also. He is such a "spaz". He gets so excited when I am ready to feed him.
No one can tell us that a "fish" is not entertaining!
