GloFish Shark Care Information

Sharing is caring!

The popular GloFish have been around for a few years, very popular with hobbyists who want to build a colorful tank without spending a fortune on expensive exotic fish species. The latest addition to the GloFish stable is the GloFish shark. We will focus on this variant in this article.

In this guide you will learn more about GloFish and the GloFish shark in particular. Here's how to care for these beautiful fish, including tank mates, feeding them, water conditions, and more!

What are GloFish?

GloFish are simply freshwater aquarium fish that have been genetically engineered to give them a brilliant fluorescent color. You can get GloFish in the following patented colors:

  • Electric green
  • Starfire Red
  • Cosmic blue
  • Sunburst orange
  • Moonrise pink
  • Galactic purple

Bioluminescence

Contrary to popular belief, GloFish are not injected with dyes or otherwise artificially colored.

GloFish was developed by scientists in Singapore who adapted the fluorescent genes of various fish species as biomarkers to produce genetically modified fish with "natural" bioluminescent colors. After the process was perfected, it was a Texan company that filed the patent and began making fish for sale to the public.

The first GloFish were Starfire Red Zebra Danios, which first hit the market in 2003. That was how popular the fish was. The company developed other fluorescent colors and species, including GloFish barbs, Glofish tetras, and most recently, sharks.

All GloFish look like normal fish under white light, but their stunning colors come about when exposed to black and blue light. While purists don't like these man-made fish, GloFish sales now account for around 10 percent of annual aquarium fish sales.

Are GloFish Good for Beginners?

GloFish can be a great choice for beginners depending on which type you choose. Like all fish, some have more complex grooming needs than others, so potential owners must carefully study their desired fish before purchasing.

What are GloFish sharks?

GloFish sharks are similar to rainbow sharks and have almost the same care requirements.

These fish belong to the Cyprinidae family and have the scientific name Epalzeorhynchos frenatum. GloFish sharks are man-made variants of the rainbow shark, and you will not see these fish in the wild.

Rainbow sharks are found naturally in the Bangfai, Mekong, and Chao Phraya basins of Indochina. Unfortunately, the number of species is decreasing, mainly due to habitat destruction. However, the shark does not appear on the IUCN Red List yet.

Wild habitat

Rainbow sharks are basic inhabitants and live in small rivers where the substrate is made up of soft sand. The fish are omnivores and mainly eat plankton and algae.

How big do GloFish sharks get?

GloFish sharks grow to be 6 to 7 inches long.

The fish have a long body and flat belly with pointed snouts and erect dorsal fins, which gives the fish a shark-like appearance. In nature, men are generally lighter in color than women, although GloFish sharks are not as the sexes are almost the same color.

Sharks reach breeding conditions when they are about 4 inches long.

GloFish sharks can live in a well-manicured tank for anywhere from five to eight years if properly cared for and fed a quality food.

Are GloFish Sharks Aggressive?

Just like normal rainbow sharks, GloFish sharks are territorial and aggressive towards other fish that invade their space.

That said, you can keep these fish as members of a community tank, provided you have a large aquarium with lots of hiding spots and choose larger tank mates to inhabit the upper parts of the water column. Basic dwellers should be avoided as they will undoubtedly conflict with the GloFish shark.

Which fish are good tank mates for GloFish sharks?

You can create an interesting display by including peaceful species of fish that can avoid your GloFish shark and self-medicate if necessary, such as: B. Gouramis and rainbow fish.

Try using other types of GloFish like barbs and danios in different fluorescent colors to really bring your tank to life!

You can help contain your shark's aggression by putting it in the tank last so it doesn't try to claim the entire setup as its own and feel like it has to defend it from any newcomers.

Can GloFish sharks live together?

You can keep juvenile GloFish sharks together as they tolerate each other and are quite shy. However, as the fish mature they become more aggressive and are best kept as individual specimens.

These are not natural schooling fish as they are solitary fish in nature and they will attack others of their kind. When trying to keep a pair of sharks together, you need a very large tank that can provide at least one square foot of floor space per fish.

GloFish Shark Care Guide

There is no doubt that a GloFish shark will make a stunning addition to your home aquarium. However, before you set off, you need to know how to take care of them.

Read on to find out everything you need to know!

Tank size

GloFish sharks are extremely lively bottom dwellers and need a spacious tank with plenty of space to swim in. For this reason, we recommend a long, shallow tank rather than a bowl-shaped tank or a tall design.

You should also put a lid or lid on to prevent your fish from jumping out of the tank. This can sometimes happen when new fish are introduced into a setup.

Ideally, you will need a tank that is at least 50 gallons for a shark. However, if you're trying to keep more than one specimen, you'll need an aquarium that is at least 6 feet long and has a capacity of 125 gallons.

decoration

GloFish sharks need hiding places that they can claim as their territory. So include lots of overhangs, caves, driftwood, and thick plants for the fish to adopt as their own space.

The best substrate for sharks is fine, sandy gravel, which does not harm the fish when swimming at the bottom of the tank.

Filtration

In nature, sharks live in rivers where the water movement is quite strong and the water is well oxygenated. In the aquarium, you will need a mechanical filtration system that will provide good flow, and it is also a good idea to use an aquarium bubbler to add more oxygen to the water.

Filtration systems are rated in GPH. You can find this number on the product packaging. GPH stands for gallons per hour and refers to the water circulation capacity of the device. Ideally, you want a GPH that is at least four times the total water volume of your aquarium.

For example, if you have a 50 gallon tank, you would want a filtration unit that produces a GPH of at least 200. It is important to know that the GPH is based on an empty aquarium or an aquarium with only a few fish. So always choose a filter that has a slightly higher GPH than you need.

Water conditions

GloFish sharks are a tropical species, so the water temperature should be between 75 and 81 degrees Fahrenheit. The water pH should be in the range from 6.5 to 7.5 with a water hardness between 5 and 11 dKH.

lighting

Sharks don't need any special form of lighting, and a standard broadband lighting unit is fine to provide what living plants need to photosynthesize. However, if you add an LED lighting unit with blue or black light, the fluorescent colors of your GloFish will really pop!

There is also the option of the GloFish Cycle Light which offers four different light modes that will completely enhance the colors of your fish and tank decor.

Do GloFish need light at night?

No!

The lights in your aquarium are designed to provide living plants with the light they need for photosynthesis and to illuminate the aquarium so you can see your fish.

Ideally, you should turn on your plants for eight to ten hours a day. The lights should be off at night.

Diet and nutrition

GloFish sharks are omnivores that eat algae, plant matter, and some fleshy protein. These fish will eat pretty much anything offered, including tropical fish flakes, pellets, seaweed, and blanched fresh vegetables. Fresh and frozen bloodworms, brine shrimp, daphnia and more make your GloFish shark a nutritious food.

If you take in juvenile sharks, feed them quality food so that your fish grow well and keep their bright colors.

Feed your GloFish twice a day and only give what it gobbles up in a few minutes.

Disease and general health

GloFish sharks are fairly hardy fish that generally don't suffer from too many health problems, provided you keep your tank clean, properly manage water conditions, and give your fish proper, high quality nutrition.

Your sharks should be lively, active creatures that are constantly looking for algae to eat and scare away any fish that get too tight into their territory. Problems can arise when your fish becomes lethargic or loses interest in food.

Common fish diseases that sometimes affect GloFish sharks include:

I

I am more commonly referred to as white spot disease. The condition is caused when fish become infected by the aquatic parasite Ichthyophthirius multifiliis.

First, infected fish rub against solid surfaces in the tank in response to the irritation caused by the parasites. As the disease progresses, white spots develop over the fish's body, fins, and gill covers.

I can be fatal if not treated. To disrupt the parasite's life cycle, raise the water temperature in the tank to 82 degrees Fahrenheit for three to four days and add a white speck medication to the tank.

Leeches

Flukes are another common parasite that can affect sharks.

These creatures usually find their way into your tank and on your fish via plants and live food. Depending on the type of parasite, the leeches attach themselves to the fish's gills and body, and you can often see them with the naked eye.

Treat leeches by adding an anti-parasitic agent to the water.

Bacterial infections

Many species of bacteria live in aquariums and only cause problems when the fish are weakened by the effects of stress or suffer an injury that is an entry point for the bacteria.

Bacterial infections can be treated by adding an antibacterial drug to the aquarium and changing the water frequently.

mushroom

Fungi often infest fish that are kept in poor water conditions and in dirty tanks. If you notice white, fluffy growths on your fish's body, fins, or head, then most likely the problem is caused by a variety of fungi.

Fungi can be treated with antifungal drugs.

Where can I buy medicines for fish diseases?

You can buy products used to treat the most common fish diseases without a prescription at your local fish or pet store, or online without a veterinary prescription. If you can't find what you want in the store, ask your veterinarian for advice.

Preventive measures

You can help keep disease and parasites out of your aquarium by taking a few simple precautions.

Whenever you buy fish, always keep it in a quarantine tank for at least ten days and make sure it is healthy before introducing the newbies to your display tank. All new plants and decorations should be thoroughly rinsed with a solution of water and antibacterial treatment to remove parasites and bacteria.

If you are feeding your fish live food make sure the supplier is reputable, remove the food from the water before adding it to your tank, and never take live food from the environment as you will accidentally introduce parasites into your tank could.

breed

Unfortunately, it's virtually impossible to breed GloFish sharks in a home tank mainly because the fish are so aggressive. It is for this reason that the GloFish sharks you see for sale in pet stores or online are raised commercially.

Availability

GloFish sharks are the latest addition to the GloFish species portfolio.

You can buy these beautiful fish directly from the GloFish online shop and other online stores at similar prices.

Final thoughts

GloFish sharks are the latest addition to the range of brightly colored GloFish color morphs created by genetic modification.

While these bright neon fish may not be to everyone's taste, they can certainly add a splash of paint to your aquarium and are pretty easy to care for. GloFish sharks are pretty hardy creatures that have basic grooming requirements. The only downside is that they are not community fish. They must therefore choose their tankmates carefully.
