How to raise blue line hangings for beginners:

1. Three days before buying blue line hangings, the fish tank should be handled well. First, add salt to the fish tank and then soak it in two-thirds of water. The purpose is to sterilize the fish tank, let the blue line hanger have a clean home, soak it for a day, and then put the fish tank in the sun for two days.

2. The blue-wire hangers that I just bought are very fragile, so the blue wire hangers are very fragile. After the line hanger is put into the fish tank, in addition to feeding, try not to watch it in front of you for two days, as this will scare the blue line hanger. After two days, the blue line hanger can adapt to the new environment and can enjoy it to the fullest.

3. The temperature must be well grasped, and a thermometer should be prepared. Generally, the most suitable temperature for the blue line hanging is 22~24℃.
