Tropical Fishes for the apartment

People living in apartments have one thing in common generally while keeping fishes; they do not have much time to dedicate to the maintenance of the fishes. Hence here are some of the steps to avoid keeping too much tab on the fish tank while busy with work.
First thing is to do is to get an algae eater, which in turn helps in eating away most of the murkiness in the water. Next step is to keep as much of artificial environment as possible like stones, plastic sea weed, gravel etc. that removes the monotony of the fishes as they learn to interact with the environment. And lastly the tank has to be well regulated with water (hot and cold depending on the tropical fish) and plenty of room for the fishes to swim.
