Beginners raising yellow-tailed blue devil need to pay attention to these matters:

1. Due to the small size of yellow-tailed blue devil, smaller aquariums can also be stocked, but it has higher requirements on water quality. The specific gravity of seawater required is 1.022, and the water temperature is about 26 degrees;

2. The yellow-tailed blue devil does not have high requirements for feed. Animal bait, algae and artificial bait can be used, so it is very convenient to feed them, as long as you pay attention to timing and ration.
