Goldfish

Although my two goldfish, a Common Goldfish and a Calico Oranda, look very different they are the same fish. The difference is the fancy goldfish have been bred for centuries to get the shapes they have today. Even the common goldfish is special as opposed to what it looked like centuries ago in China, they were brown and black. Very few had reds and oranges so they were specially bred and now you have the current version of the goldfish. Mine are starting to get big so of course I'll need a new tank right around the holidays, pretty nice coincidence, huh? I just make sure to do frequent water changes because Goldfish are the dirtiest fish you can ever possibly have.
