Are you looking for a new fish to live in your aquarium? A Golden Roseline Shark must be a great idea due to its stunning color and simple diet requirement.

If you find this species interesting, do not miss our guide. Let’s join us and learn everything about this charming shark!

Origin Of Golden Roseline Shark

This species has different names, such as Gold Denison Barb and Gold Roseline Torpedo Barb.

The fish’s native habitat is the rugged upland streams in Southwestern India. It has started to gain the interest of fish lovers since the 1990s.

The Roseline Shark has a classic minnow-like color, with dark spots on the back and brighter spots on the belly. You can also notice red and black lines that split its body.

On the other hand, the Golden variety doesn’t have any red line. Instead, it’s famous for its yellowish body, with red splotches on the dorsal fin and yellow splotches on the caudal fin.

The absence of melanin is most likely to blame, leading to a brilliant fish with hues that look like they are a kind of coral reef.

This species is relatively small, from 4.5 to 5 inches in size. However, its stunning color makes it outstanding in the aquarium.

How To Feed A Golden Roseline Shark?

These fish are omnivores, making their feeding time easy. They can eat everything you put in the tank. So feel free to feed the tiny invertebrates, algae, and even insect larvae.

Dried foods such as pellets and flakes are the handiest option. You can easily find them in any pet store. Their low price is also a big plus.

Yet, their nutritional content decreases significantly after the production process.

To ensure that your pet can thrive, try to give them nutritious and well-balanced diets. Please do not feed them only dried food because they would prefer a healthful supplement.

Fresh and frozen meals, such as brine shrimp and bloodworms, are great options because they have all of their nutritional value.

Another method to give your pet a diverse diet is to include green veggies. You can chop broccoli or zucchini into small bits so that your pet can consume them easily.

A diversified diet keeps your pet healthy and enables them to display their gorgeous colors. Carotenoids-rich meals are beneficial for making the creature attractive.

These fish can eat many kinds of food

Best Water Conditions And Temperature

As a fish owner, you may understand how important it is to maintain proper water parameters. The health of your pet depends on having consistent parameters.

The water parameter ranges below are ideal for Roseline Sharks:

  • Temperature: 60-77° F
  • KH level: 4-10,
  • pH level: 6.8-7.8

Since this creature can grow quite huge, it may outgrow a 55-gallon tank quickly.

Instead, you’d better go for a large-sized tank so that your active pet has enough space to swim.

This species loves clean water with high oxygen content. It cannot handle high concentrations of organic debris. Hence, frequent water replacements and tank cleaning are essential for its health.

You can learn some water replacement tips right here:

If possible, use a powerhead or spray bar to create water movements within the tank. Your pet loves to swim across the waves.

Another thing for setting up the tank is that this fish may jump out. Hence, remember to cover the tank with a lid to avoid this problem.

Try to give your pets the best conditions

Different Between Male And Female Golden Roseline Shark

You can distinguish between male and female fish by checking their body size and color.

A female has a rounder, heavier, and bigger body than its male counterpart. Meanwhile, the male fish is smaller, but its colors look brighter.

How To Breed Golden Roseline Sharks?

Roseline Sharks are an endangered species; thus, breeding them in captivity is difficult.

These fish are endangered creatures. Hence, many people believe that breeding them is a tricky task, but you may find some exceptions.

Some commercial systems succeeded in breeding the fish. However, carrying out this process at home is so challenging that its successful cases remain rare.

Do not expect too much if you want to breed them by yourself. Commercial breeders have a higher success rate because they employ complicated systems and hormones.

If you still want to breed your pets, we will recommend these tips:

  • Reproduction occurs more commonly in communities of 15 or more. Reducing the pH level to 6.5 may aid in spawning.
  • Dense vegetation is also important. It would help if you had java moss and other plants during this time to protect the fish eggs.
  • If you get as far as growing the fry, the safest option is to keep the parents apart to prevent them from eating their eggs. They are not caring parents.
  • The baby Roseline Sharks need small foods, such as infusoria. Try to feed them this stuff until they grow bigger.
  • They’ll need to eat little things like infusoria until they grow bigger.

Vegetation should be dense

Typical Behaviors Of Roseline Sharks

Despite the word “shark” in their name, these fish are peaceful. They can live in harmony with their tank mates and like to swim in groups.

However, it doesn’t mean that they never get angry. Sometimes, you may see them chase their tank mates because these fast swimmers do not like slow-swimming fish.


Golden Roseline Sharks are fantastic for fish keepers due to their elegance, friendly character, and many other factors. Their aesthetics will enhance and compliment the attractiveness of your house.

Hopefully, our guide has helped you picture what this fish looks like and how it grows. Please also bear the caring tips in mind so that your pet can thrive.
