GloFish® Rainbow Sharks are vibrant, easy-to-care-for fish that coexist harmoniously with other GloFish and community fish. These bottom feeders not only add a splash of color to your tank but also help keep it clean by eating leftover food, algae, and small snails. Perfect for enthusiasts looking to enhance their aquatic display, GloFish Rainbow Sharks are a striking addition to any large aquarium.

These impressive fish grow up to 4 inches, making them the largest GloFish variety. They thrive in tanks of 30 gallons or more, with one shark per 30-gallon tank. In tanks over 40 gallons, multiple sharks can coexist if there's enough bottom space. Jumbo Sharks, at least 5 inches long, need 55 gallons per shark for optimal health.

Choose your GloFish® Rainbow Shark color. They are available in:  Sunburst Orange®, Electric Green®, Cosmic Blue®, and Galactic Purple®. 

GloFish® Rainbow Shark Quick Guide: 

  • How many fish can I have?
    • Keep one shark in aquariums of 30-40 gallons with ample space and hiding spaces
    • Keep one JUMBO shark per 55 gallons of water in your tank
    • To keep multiple sharks you'll need a large aquarium with ample bottom space and shelters
  • What do I feed them?
  • How do I make them pop in my tank? 
    • Put a lot of blue lighting in the tank. This is especially helpful for the Cosmic Blue® fish. Additionally, you can get the light here.

Make sure your order meets the sitewide minimum of $69 on GloFish, including fish, food, and water care products.

Lonely Shark

So I bought a red shark. He was fine amongst the bus station of fish in my huge tank. A week later I added two angle fish and another 5” shark. This one blue. OMG it was the shark reunion of all time. Best buds. They race each other all around the tank. So, you cant’t buy just one!

My shark came missing a fin

The shipping was good and the fish are all alive and well. But there was the issue that my shark is missing a fin. There is no wound so it was an old injury. He seems to be liking the tank but was constantly hiding for a week so I just really noticed.

Preferred Place to Buy

This is the my fourth shark. My first was directly from glofish, it jumped out during tank water refill and unnoticed. Sadly as it was quite large. Bought 1 from each petsmart and petco to get quicker and locally, but both died within 2 months. I have had best luck with buying my fish direct, great service.

Where was the heads up?

Purchased 4 glofish. 1 was a rainbow shark. I left the bag open to slowly add tank water to it. We were working on acclimating the fish. 12 hours after getting them, the rainbow shark jumped out of the bag. I was not advised of this or I would have taken steps to prevent this. My son found him on the floor dead. He is devastated. Ive never had a jumping fish and really wish someone told us this so we could be mindful. :( RIP Clark the Shark.

I love my glowfish when I received them. They all were alive, including my shark. They look wonderful in my tank.
