Essential Care Tips for All Fish Species

No matter which fish you pick, these tips help keep your tank in good shape:

• Keep water clean: Use good filters and do regular water changes (about 25% each week). Check pH, ammonia, nitrite, and nitrate.
• Feed the right amount: Do not add too much food as it can spoil the water. Serve small amounts that match each fish’s diet.
• Set up the tank: Use real or fake plants, rocks, and hiding spots. This makes the world of the tank more like nature.
• Watch fish for signs: Bet on their behavior, shape, or color; these may show if they fall sick. Let new fish stay alone for a short time.
• Choose the tank size: Match it with the fish so they have space to swim.
