My teenage son spends most of his time arranging his aquarium. He is not contented with the plant or the number of fish in it. He regularly adds fish and other accessories to beautify it. He’s maintaining the aquarium for several months now and seems to know different kinds of fish fit for aquarium management. If he owns a guitar, he would probably know parts of a guitar. Today, he removed the plants and pebbles and replaced them with stones and drift wood. I hope he does not get bored with its present setup or I might be seeing a different arrangement in a day or two.
