The Swai Fish, or Iridescent Shark, is a rather unremarkable fish that is typically farmed in Asia. However, it seems to create a bit of controversy in what contexts it appears. Whether it is to be kept in an aquarium or to be eaten at the dinner table, the Swai Fish has opposing viewpoints. The Iridescent Shark is not really a shark but gets its name because it resembles on in appearance. It can be found on the market as Swai Fish and shark catfish. It is a member of the catfish family. As a juvenile, the Swai Fish radiates a glow from the edges of its fins, thus given the name Iridescent Shark. It can grow up to four feet in length and weigh up to nearly 100 pounds. They are omnivores and will eat other fish, crustaceans, and different types of water plants.
Alternatively you can use an auger to speed up the process of digging the fence post holes. Make sure you make the holes sufficiently wide enough for the posts, e.g. approximately 8-10 inches in diameter. After digging a fence post hole, set a post into the center of it and use a 4 to 6 foot level to plumb the pole. Also make sure it is in line with the other fence posts. Using a string line along the length of the staked out fence line is helpful in positioning each fence post.
Drive or auger & tamp both end posts (or corner posts) for the run you are fencing. Concrete or gravel may be used. Do not concrete within the top 4 inches of the ground. Posts should be set with 4 feet, 6 inches above ground and 3 feet, 6 inches below ground.Wet or sandy soils may require 5-6 feet in ground. Establishing the fence grade: Tie one end of a guide wire (12 Â½ ga.nstalling line posts: Set line posts at 10- to 15-foot spacing unless you are using high tensile fence. High tensile can be 15- to 20-foot spacing. Post spacing will be determined by terrain, type / size of post, bends in the fence and animal pressure. T-posts: weight should not be less than 1.25 lbs.
