I think my fish may be sick. What should I do? There are many factors which may contribute to the health of a fish. Because of this, if you have specific questions regarding a potential illness, the best suggestion we can offer is to contact a local veterinarian who works with fish and/or your local fish store, as they will often be the best sources for guidance in such matters. Please remember that any illness or symptoms should be diagnosed the same way as they would be for the GloFish’s non-fluorescent counterpart.

Below are answers to the most common questions we receive about setting up and maintaining home aquariums. In general, if you have a specific question about your particular aquarium, the best source for guidance is your local fish store. In addition to checking with local experts, you may also find the tips and information on our GloFish Care page to be helpful.
- What are the recommended pH levels? Aside from their brilliant color, fluorescent fish are the same as other fish, and accordingly, the pH level requirements are the same. While the recommended pH level varies somewhat depending on the source, a pH range between 6 and 8 is generally fine. For additional information on this, we would recommend checking with your local fish store.
- Do I need to use a filter? 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.
- Will blue, actinic, or black light harm my fish? We have never observed or heard of any problems related to the use of any of these lights with our fish. As with any light, however, it is important not to keep it on continuously. For additional lighting and display information, please visit our GloFish Display page.

- Badmantropicalfish.com. One point in particular to note is that our GloFish® Electric Green® Barbs can potentially become aggressive if they are not kept in groups of five or more. This is not necessary with our GloFish® Danios or GloFish® Tetras; while they prefer to be in groups of five or more, they will not become aggressive in smaller numbers.
- Like their non-fluorescent counterparts, GloFish are freshwater fish. They should not be placed in a saltwater environment.

As we hope you will understand, it is necessary for us to protect the very significant investment we have made in the development of GloFish. For more information on the patents and related intellectual property rights that cover our fish, a complete licensing statement can be found on our License page.
- No, they are born beautiful! GloFish® fluorescent fish are traditionally bred; they are not dyed, injected or individually altered in any way. Their unique color is a hereditary trait that is passed from generation to generation, just like any other genetic trait.
