Denison Barb – The Peaceful Barb

With the large variety of fish that can inhabit a fish tank, it can become overwhelming trying to decide the right ones to put inside to inhabit the enclosure. Especially when hearing about barbs (more specifically) tiger barbs have a reputation for being brutes and aggressive in an aquarium. There are more barbs that are also aggressive but there are some that are nice and gentle. Specifically, the Denison Barb.

Temperment & Size

Denison barbs sometimes known as Rose Line sharks look like a dominating force inside of an aquarium but they are one of the most beautiful and gentle animals you can keep. It is of course not recommended to keep them with little fish like neon tetras or ember tetras because they will become lunch, but they’re perfectly welcome in a community aquarium filled with larger peaceful fish.

These fish love to be in larger groups preferably 5 or more fish. Also, do not forget to keep a good lid on your aquarium because these fish are known to be jumpers! Because of their love for being in groups and active personalities, I would not recommend putting this fish in anything smaller than 50 gallons of water.

The Denison Barb is different from your typical barb. This fish is far longer and more streamlined. They are normally found in fast-moving streams in the wild and appreciate higher oxygen levels in an aquarium. They also grow to be about 4 to 6 inches when they are full-grown.

Feeding & Aquarium Requirements

The Roseline Shark will happily take most foods and giving them a large variety of food only benefits them. They will gladly eat bloodworms, fish flakes, pellet food, and algae flakes/wafers/pellets. They are safe to keep with live plants and will not go out of their way to eat them! They’re omnivorous fish so giving them many options will keep them happy!

They enjoy an enclosure with a pH between 6.8 – 7.8 and temperatures ranging from 60 – 77 degrees Fahrenheit. They should be right at home with other tropical fish because for the most part, their water parameter needs are quite similar. Overall, they are quite easy to care for as long as they are introduced into an established aquarium.

Final Thoughts

Denison barbs are incredibly active fish and are insanely beautiful with their gray black and red coloring. They will make any aquarium seem more vibrant and bring new life to the setup. Keep them in nice groups and feed them a variety of food and they should be happy for quite some time!
