Question 1

How many Endler guppies should I start with?

Accepted Answer

Start with at least 6 fish for a comfortable group dynamic. If you want to avoid breeding, go all-male; if you're fine with fry, aim for 1 male to 2-3 females.

Question 2

Can Endler guppies live with bettas?

Accepted Answer

It's risky. Some bettas ignore Endlers, but many see them as fin-nipping targets or prey. If you try it, use a tank of 10 gallons or more with heavy plant cover and a backup plan to separate them.

Question 3

Do Endler guppies need a heater?

Accepted Answer

Yes, in most homes. Endlers need water between 72-82°F, and room temperature often drops below that range overnight or in winter. A small adjustable heater keeps them stable.

Question 4

How often do Endler guppies breed?

Accepted Answer

Females can produce a new batch of fry every 23-30 days once mature. Because females store sperm, they can keep breeding for months after being separated from males.

Question 5

What do baby Endler guppies eat?

Accepted Answer

Fry can eat crushed flake food, baby brine shrimp, or powdered fry food right from birth. Feed them small amounts several times a day for faster growth.

Question 6

Can Endlers live in an unheated tank at room temperature?

Accepted Answer

Only if your room stays reliably within 72-82°F year-round. For most homes, a small heater is cheap insurance against cold snaps that can stress or kill Endlers.
