Glow rocks
Glow rocks are often made of resin or plastic and contain phosphorescent material that absorbs light during the day and then emits it at night. This can create a beautiful effect in an aquarium, but it's important to make sure that the glow rocks are safe for guppies. Some glow rocks can contain harmful chemicals that can leach into the water and potentially harm the fish. It's important to choose glow rocks that are specifically designed for aquariums and are made of non-toxic materials.
Plants
Plants can be a great addition to a guppy tank, as they provide hiding places, help to reduce stress, and can improve the water quality by removing toxins. However, it's important to choose plants that are safe for guppies. Some plants, such as Amazon sword plants, can be harmful to guppies if they eat them. It's important to do some research before adding plants to your guppy tank to make sure that they are safe for the fish.
Guppies
Guppies are generally peaceful fish that are easy to care for, but they do have some specific requirements. Guppies prefer warm water (between 72 and 82 degrees Fahrenheit), a pH level between 6.8 and 7.8, and a hardness level between 5 and 20 dGH. They also need plenty of swimming space, so it's important to choose a tank that is at least 10 gallons in size for a small group of guppies.
Compatibility
Guppies can be compatible with a variety of other fish, including tetras, barbs, and rasboras. However, it's important to avoid housing guppies with aggressive fish, such as cichlids, as they can bully and even kill guppies.
Overall
Guppies can live in a tank with glow rocks and plants, but it's important to make sure that the glow rocks are safe for the fish and that the plants are non-toxic. It's also important to choose the right tank size, provide the appropriate water conditions, and select compatible tank mates for the guppies.
