Note: Different aquatic organisms have different requirements for habitats. Therefore, before buying your favorite freshwater fish, you should study their habits and configure a fish tank suitable for their life. LICG (Netherlands National Companion Animal Information Center) gave the following six tips:

(1) Different fish have different requirements for water. Including water temperature, pH and hardness of water, so the water quality of fish tank should be monitored regularly.

(2) Not all fish can be kept in the same tank. Different kinds of fish have different personalities, some like water, some like underwater, some are impatient, and some are leisurely. You need to consider how to mix different kinds of fish in a fish tank.

(3) The fish tank should not be too crowded. 1 liter of water can raise 1 cm of fish at most. Fish are gregarious animals, raised from two families.

(4) Do not use a fully transparent fish tank. A transparent fish tank on all sides will make fish feel insecure, so at least one background wall is needed, and it is best not to use a round or vertical fish tank. Plant some aquatic plants in the fish tank to give the fish a hiding place.

(5) Basic equipment needs to be complete. Including water pump, filter, thermometer, heater, lighting lamp, etc.

(6) Be patient. First configure the fish tank, adjust the water quality, and then buy fish to raise fish after the fish tank environment is suitable for fish life.
