The feeding method of red swordfish is as follows:

1. The fish tank for raising red swordfish must use a slightly larger rectangular glass fish tank, and the water temperature should be controlled at about 25-28 ℃.

2. When the red swordfish is hypoxic, you can turn on the oxygen machine to supply oxygen. If there is no oxygen machine, change some water for the red swordfish and find a suction pipe to suck away the tank. For the dirty things at the bottom, you can change the water by one-third or one-half of the water. If you change too much, the red swordfish will not adapt to it. Try not to touch the red swordfish when absorbing or adding water, so as not to hurt its fins.

3. You can feed red swordfish with professional fish food, and bread crumbs can also be used. Red swordfish are not very picky eaters.
