Can Silver Arowanas Eat Antarctic Krill?

Yes, silver arowanas can eat Antarctic krill. Unlike golden arowanas, silver arowanas do not require shrimp to enhance their color, allowing them to consume a wider variety of shrimp. Therefore, Antarctic krill is a suitable food option for them. However, it's crucial to ensure that any sharp parts are removed before feeding to prevent injury to the arowana's digestive system.

 

Silver arowanas have large, pinkish, semi-circular scales with a metallic silver body, often interspersed with hints of cobalt blue, blue, and cyan, giving them a shimmering appearance. They primarily feed on live foods such as mealworms, small fish, and shrimp. Antarctic krill, being small in size, are a great source of high-protein, low-fat nutrition, packed with essential minerals and amino acids, making them beneficial for supplementing a silver arowana's diet.

Six Shrimp Varieties Suitable for Silver Arowanas

1. Sea Shrimp

Sea shrimp are transparent with a body length of about 18-24 cm, slightly flattened on both sides. Females are brownish-blue, while males are slightly yellowish. They have a carapace covering their body, a wider and harder head and chest, and a pair of eyes on each side of the rostrum. They have five pairs of appendages on their head, with the second pair being longer.

2. River Shrimp

River shrimp have paddle-shaped swimming legs and a fan-shaped tail. Their legs are slender, and their gills are feathery. They have a hard exoskeleton that provides protection.

3. Penaeus Chinensis (Fleshy Shrimp)

These shrimp are larger, ranging from 13-24 cm in length. Males are yellow, and females are bluish-green. They have a thin, smooth, and nearly transparent carapace. Their rostrum is straight, and the lateral ridge typically does not extend beyond the middle of the carapace.

4. Grass Shrimp (Black Tiger Shrimp)

Grass shrimp, also known as black tiger shrimp, belong to the Penaeidae family. The cephalothorax has antennal spines, hepatic spines, and gastric teeth. The hepatic ridge is straight and clear. Their body color is unique, with alternating dark green, dark brown, and light yellow horizontal stripes, which are particularly noticeable on the abdomen.

5. White Shrimp

White shrimp are about 8 cm long. The upper part of the rostrum has 6-9 teeth, while the lower part has no teeth. Their body is light brown, the abdominal limbs are bright red, and their body surface has many depressions and short hairs.

6. Antarctic Krill

Antarctic krill are found in the Antarctic waters of the Southern Ocean. They feed on tiny phytoplankton, converting the energy from primary production to sustain their life cycle. They are also exceptionally nutritious.Don’t miss out on this:Pet Breeding
