Okay, I have this Small Aquarium in my room. I have two goldfish, and I would like to buy a Glo-Fish and put it in the same aquarium. Is that safe? Like, will the goldfish eat the Glo-Fish? will the Glo-Fish Cause bad things for my Goldfish? My two goldfish are the same size, 1 inch long, and 1 centimeter in height. (about) Please help me to see if i can put a Glo-Fish in my aquarium!
