How Do You Take Care Of GloFish?

Taking care of GloFish is a very straightforward task. You just need to maintain the balance between everything, including the food, lighting, water parameter, and substrates. 


The diet of GloFish species needs to be balanced with all kinds of foods. Some food needs to be fed on a daily basis, and some on a weekly basis. But the proper diet and regularity should be maintained with the proper nutrients.  

Nutritional balance makes sure the proper growth and breeding of the fish. You need to include food containing high carotenoids & beta carotene as it will keep your GloFish’s color lovely and vibrant. 

Feed regular items twice a day but do not overfeed them. The fish need to finish the food within 90 minutes. Do not give the frozen food directly to the fish. Remember to take time and soften the food first.  


When it comes to light, let the first tell you its importance in GloFish’s life. Actinic light, which contains the component of sunlight, is required for GloFish as they have a high color temperature (5000 – 6000 Kelvins). 

Blue light is the perfect actinic light for the GloFish, and they also help to direct them with the understanding of day and night. To balance the cycle, you need to provide them with 12 hours of light and 12 hours of darkness. 

As lighting cycle will regulate the food and sleep pattern so that they stay healthy. The blue light helps the GloFish with the fluorescent quality of them as they absorb the light, which makes them glow under the black light.  

This is the reason experts recommend GloFish lovers to set the light arrangement in such a way that in the daytime, the GloFish gets enough blue and white light because it helps them with light absorption.

It further helps the GloFish emit light under the presence of back light by glowing in vibrant neon color.  

Water Parameters

The fluctuation in the water parameters can not only make the GloFish stressed but can cause death.

You need to make sure all the species are provided with the average level of temperature pH level. The KH, GH, and nitrate levels should also be maintained. 

You also need to change the water regularly, and adequate filtration is required to keep your GloFish healthy.

Check the water temperature regularly, test the water quality once in a week and try to change 20 to 25% of the total water every two to three weeks.


Substrates help the fish to feel the tank environment as naturally as possible. It would be best if you keep plants and other non-reactive matters in the tank so that it makes the GloFish comfortable to live in. 

Substrates like gravel, marbles, stones, sand and other non-reactive matters are a great choice for GloFish.

When you need to keep aggressive and non-aggressive species of GloFish together in the same tank, remember to keep enough hiding spots for them. 

How Long Do GloFish Last For?

The lifespan of the GloFish can vary depending on the type of GloFish. On average, the lifespan is considered to be 4 to 8 years.

The lifespan can also differ depending on your level of care and support. 

Let me provide you the chart of different GloFish mentioning their lifespan;

This is the reason the GloFish does not require light at night. Remember to give them light for 12 hours a day and keep them in a dark area for the rest of 12 hours.
