The way to improve it, if the water is hard or chlorine-rich, is to buy a heating rod and set the temperature at 30 degrees to make the water explode quickly, that is, to make the new water become old water as soon as possible. Or the tap water newly connected by indigenous methods should be exposed to the sun for more than 2 hours, and it is best to put it straight for 3 days. This is water treatment.

Feeding: It's better to buy some brands of feed particles, which are safer and more reliable. Generally, the loose ones are damp or spoiled, and the fish will die if eaten. Feed fresh live food. If you feed live shrimp, you must remove the head and shrimp, because these can kill the fish.

Lighting is something to improve the enjoyment. It is optional. If you must buy it, you are advised to buy a lamp with the color of your ingot. For example, if your ingot is red, just buy a Taiwan Province tube. It costs about 70 pieces with a shelf, which is about 600 pieces long. If your cylinder is large 1 m or 800 or 1 m 5, you can also choose it.
