An aquarium includes a filter housing disposed in a container, the housing includes a number of spaced guide fins extended into the housing and arranged to form a peripheral passage around the guide fins, a filter member engaged in the guide fins, and a water pump attached to the housing for pumping the water into the passage of the housing and for guiding the water to flow through the guide fins and to flow from various directions into the filter member and for allowing the water to be guided to flow through an outer peripheral portion of the filter member and for preventing the water from flowing through only a small portion of the filter member and for preventing the filter member from being quickly blocked by dirt or contaminant.
