Why is my iridescent shark turning white?
Probable reason is your water parameters and other conditions are not right for the fish. These fish (Pangasius hypophthalmus) are usually sold as immature juveniles. They do not usually last long in the aquarium because they usually die of organ failure caused by being kept in the wrong conditions. They are not sharks but large (edible)catfish and under the right conditions will grow to over 36 inches, so they need a minimum sized tank of around 10 feet long with suitable height and depth to match the length. They need a pH of around 7, a dGH of around 10 and a temperature of around 75F. Maybe now you can understand what is wrong with your "Iridescent shark"

Sharks have a skeleton and that skeleton includes a spine, so they are classed as vertebrates. It's just that the skeleton is made of cartilage rather than bones.
Sharks are VERTEBRATES. They do have a backbone and are fish.
Sharks belong to the phylum Chordata, and subphylum Vertebrata, and are true vertebrates. Their skeleton is made of cartilage, not bone, but they have a vertebral column. Although the vertebral column is made of cartilage, it is strengthened by tesserae (crystal blocks of calcium salts) which gives it a similar toughness to the bone found in other vertebrates. Tesserae is also found strengthening the sharks jaw and gill arches.
it is a vertebrate because it has a backbones

So dolphins are faster then sharks!

Is there a procedure to keep sharks away from the beach area?
A common procedure used at popular swimming beaches is shark nets way out in the water, parallel to the sand, yet this is a poor procedure as it becomes deadly to marine life, and doesn't even always work. Shark nets are indiscriminate killers, killing marine life such as seals, turtles, stingrays, dolphins, and even whales in addition to sharks.
Shark nets are simply a false security blanket for the public. The majority of sharks that are caught in the nets are on the beachside on their way back out to sea. They simply don't work. They should be banned and removed immediately from all coastlines.
hopefully a new, procedure can be made
