Question 1

How many fancy guppies should I keep together?

Accepted Answer

A group of five or six adults can live in a cycled 10-gallon aquarium, though a 20-gallon tank provides more stable water and room. For mixed sexes, keep about two or three females per male.

Question 2

Do fancy guppies need a heater?

Accepted Answer

Yes, unless the room keeps the aquarium consistently within the required range. A thermostatic heater helps maintain a stable temperature of about 74–78°F and prevents stressful nighttime changes.

Question 3

Can I keep only male guppies?

Accepted Answer

Yes. An all-male group provides color without producing fry. Keep several males, provide plants and swimming space, and watch for persistent chasing or fin damage.

Question 4

How often should I feed fancy guppies?

Accepted Answer

Feed a small amount once or twice daily. The fish should finish each meal within about one or two minutes. Use a quality staple food and add small live or frozen foods for variety.

Question 5

How often do fancy guppies have babies?

Accepted Answer

A healthy female may produce a brood roughly every four weeks, though timing varies. Females can store sperm and may deliver several broods even after males are removed.

Question 6

Why are my guppies dying in a new tank?

Accepted Answer

Ammonia or nitrite from an uncycled aquarium is a common cause. Test the water immediately, perform an appropriate conditioned water change, reduce feeding, and seek professional help if fish remain distressed.

Question 7

Can fancy guppies live with bettas?

Accepted Answer

The pairing is risky. Bettas may attack colorful male guppies, and active guppies may bother a betta. A different peaceful companion is usually safer, especially for beginners.
