A great name for a shop, I never would have guessed it would be a fish/pet store. They have a large selection of fish, fresh and saltwater. They also have turtles, lizards, a lonely toucan, and a very sad owl. Despite the disrespect for wild animals (that should never be pets), the staff is very knowledgeable and friendly. They were very polite when I complained. If you ever wander by this store, I hope you'll say something as well. I know every other customer just says 'kawaii' (how cute) and walks away (both animals are extremely expensive and will probably live the rest of their lives in the store). If you are purchasing fish, however, this is the only shop in Shimokitazawa.
