GloFish® Fluorescent Fish Care
GloFish are like their non-fluorescent counterparts, just with a brighter disposition. They are exactly the same in terms of care, including everything from general care and temperature preferences to water quality and nutritional needs. With a little care and attention, your fish will be a happy, healthy companion for years to come.
The following tips are general suggestions to help ensure a great experience for both you and your GloFish. Please contact your local pet supply retailer with any questions or concerns related to your GloFish fluorescent fish care.

It is very important to prepare the water before adding fish to an aquarium. Most tap water contains harmful chemicals (like chlorine and ammonia), which can be dangerous for your fish and should be neutralized. Another helpful preparation step, known as “cycling,” will establish beneficial bacteria in an aquarium and reduce the any chances of your fish having an adverse reaction to their new environment. You can view detailed information about the cycling process here.
Your local pet shop will be able to advise you on the best ways to neutralize the water and cycle your new aquarium. They can also suggest decorations that will make a fun and interesting home for your GloFish fluorescent fish!

When you have prepared the water and are ready to introduce your fish to its new home, there are several important steps you should take to make sure the transition is both safe and comfortable for your fish:
- First, avoid extreme temperature variations or prolonged travel time when transporting your fish from the pet store to your home.
- Once you have arrived home, while keeping the fish enclosed in the bag from the pet store, float the bag in your aquarium. This will allow the temperature of the water in the bag to come closer to that of the tank.
- After the bag has been floating for 30 minutes, open the bag and add about one cup of aquarium water every 10 minutes, until the volume of water in the bag is doubled. This gradual process will help your fish to adjust to the difference between the water that was in the pet shop and the water that is in its new home.
- Once the fish has had enough time to become accustomed to the new water conditions, you can release it into the tank by carefully discarding the water from the bag through a fish net and quickly placing the fish into the tank. It may be shy for the first few minutes as it explores its new home, but it will adjust within a short period of time.
Be careful not to overfeed your fish! Any food the fish does not eat will pollute the tank. Experts suggest feeding your fish relatively small amounts of food once or twice a day. If they eat all of the food within a few minutes, it is okay to add a bit more, as long as they eat all (or at least most) of it within a short period of time. Over time, you will get a better idea for how much food the fish can eat, and you can adjust the feeding amounts to fit the needs of your fish. The experts at your local pet shop can demonstrate good feeding practices. In terms of nutritional needs, please remember that GloFish® fluorescent fish are the same as their non-fluorescent counterparts. Flaked food and live food such as brine shrimp are good options. We recommend GloFish Special Flake Food as a feeding source for our Tetras, Danios, and Barbs. For the GloFish Sharks we recommend Tetra PlecoWafers™.
Every kind of fish has its own temperature preferences. In general, GloFish fluorescent fish can live in a fairly wide temperature range, anywhere from 64-86°F (18–30°C), but prefer temperatures of 72-80°F (22-27°C). Depending upon the temperature of the room in which your aquarium is maintained, an aquarium heater may be helpful to maintain this temperature range. The most important thing to remember is to avoid quick temperature changes, since these can be fatal for the fish.
About 25-50% of the water in your tank should be changed at least once a month. This is in addition to replacing water lost to evaporation. This can be broken up into small weekly changes. Of course, if it appears to be dirty, the water should be changed more often and feeding habits may need to be modified to reduce the pollution. When changing the water, be sure to neutralize the chemicals that are present in the tap water, and bring the water to the same temperature as the water in your tank before adding it. This is very important to remember since a quick temperature change can be fatal for the fish.

Illumination during daylight hours is important to reduce stress and disease, and it will also help you bring out the brightest possible color in your fluorescent fish. The light should not be left on throughout the night, however, as fish benefit from alternating periods of light and darkness, just like people.
We strongly recommend using a filter. Because an aquarium is a living biological system, it will produce various toxins that should be removed from the water. A filter helps remove these toxins and also houses the majority of the beneficial bacteria, which are vital to maintaining healthy, happy fish. Please check with your local pet shop for advice on what type of filter would work best for your aquarium. For additional information on aquarium filters, please visit AquariumOwner.com.
GloFish are relatively hardy, easy to keep, and get along well with other fish. However, not all fish are this way, so if you have other fish in your tank or are adding new fish to your GloFish tank, be careful to choose fish that can all live together in a similar environment. Here are a few key points that may be helpful: (1) Like their non-fluorescent counterparts, GloFish (other than Sharks) are schooling fish and should ideally be kept in groups. This is particularly important with GloFish Barbs (Electric Green® and Starfire Red®), which can potentially become aggressive if they are not kept in groups of five or more. GloFish Sharks can be semi-aggressive towards one another, so we advise keeping only one shark per aquarium. They can, however be housed along with other GloFish Tetras, Danios, and Barbs. (2) Be sure not to crowd too many fish into a tank. (3) Please avoid keeping fish (even just one fish) in a small bowl. Recommended stocking densities vary depending upon the literature source, tank configuration, filtration system, and other factors, so making a specific recommendation is difficult. We recommend consulting with the experts at your local fish store before starting a new aquarium or adding to an existing community.
GloFish fluorescent fish thrive in all types of settings, including homes, offices, and classrooms. However, it is important that you do not place the tank in direct sunlight or close to a heating or cooling source. This will cause algae growth and can cause unwanted temperature changes.
For the best way to Experience the Glo!®, we suggest the following:
Daytime Viewing – We recommend a blue wavelength light (such as those available on GloFish Aquarium Kits and with GloFish LED Lighting). A blue light will give GloFish an exciting and uniquely fluorescent look, particularly in low lighting environments. Alternatively, a traditional white aquarium light (such as a fluorescent or halogen light) will work well for daytime use. Whichever light is used, please remember that GloFish® fluorescent fish absorb light and then re-emit it, so they will appear brighter and more vibrant as the amount of light is increased.
Nighttime Viewing – We recommend a blue light, such as those available on GloFish Aquarium Kits and with GloFish LED Lighting. A black light can also be used in a room that is completely dark and will create a unique and fascinating appearance. At the same time, please remember that the black light will only be helpful in a completely dark room. Using a black light during the daytime or in a room that is only partially dark will result in far less than optimal viewing.
Please note: Aquarium lighting should not be left on continuously, as fish benefit from alternating periods of light and darkness, just like people.
