Can GloFish Live Peacefully with Guppies?

Yes, they can but it’s not a straightforward yes for all types. It’s a bit tricky to answer without clarifying something important first. GloFish are not a single species of fish but a group of different species genetically modified to glow. Therefore whether GloFish can get along with guppies really depends on which specific GloFish species we’re talking about.

Let’s break it down by looking at different types of GloFish:

Betta GloFish – Betta fish are known for being quite possessive and can act aggressively towards other fish and including the peaceful guppies. Male Bettas are particularly known for their aggressive nature towards each other. It’s possible to keep Betta GloFish with guppies but it would require constant supervision to prevent any harm. It’s generally not recommended because of the high level of care needed.

Tiger Barb GloFish – Tiger Barbs are medium-sized fish that are almost twice as big as male guppies. The main issue with Tiger Barbs is their tendency to bully other fish particularly those that are peaceful like guppies. They also tend to pick on fish with large fins and making guppies a target. Mixing them with guppies is not advisable.

Rainbow Shark GloFish – Despite their stunning appearance. Rainbow Sharks are not good companions for guppies. They can grow to be quite large and around 6 inches and are known for being territorial and aggressive. They often harass and can harm smaller more peaceful fish such as guppies. It’s best to avoid keeping them together.

Zebra Danios GloFish – Zebra Danios are small and peaceful fish that live well in groups just like guppies. However they prefer cooler water temperatures than guppies which like warmer waters. Because of this temperature difference they’re not the best match for sharing a tank.

Black Skirt Tetra GloFish – These Tetras are peaceful, grow up to about 3 inches, and are omnivorous. They’re known for doing well in community tanks and can coexist peacefully with guppies. If you’re considering adding GloFish to a tank with guppies, Black Skirt Tetras are your best bet for a harmonious aquarium.

Lastly they need places to hide and feel safe. You can put plants and little caves in the tank. This gives them spots to go when they want to be alone or feel scared. It also makes the tank look nice. Plants are good for the water too. They help keep it just right for the fish.
