How to raise betta fry outdoors. (Ponds, flower pots)

Low-Tech Grow-Out Solutions for Warm Seasons

Outdoor grow-outs offer fast growth, strong immune systems, and natural hunting instincts — especially during summer.

What You’ll Need:

Large flower pot, storage bin, kiddie pool, or shallow pond (10–50 gallons)

Live plants (hornwort, duckweed, guppy grass)

Mosquito net or mesh cover

Dechlorinated water

A few snails (optional cleanup crew)

Partial shade or indirect sunlight

Steps:

1. Set up container in a safe, shaded area.

2. Fill with conditioned water and add floating plants.

3. Seed with live foods (daphnia, scuds, mosquito larvae).

4. Allow the system to establish for a week before adding fry.

5. Transfer 3–4 week old fry to grow-out.

 

Tips:

Use a net to prevent predators (cats, birds, raccoons).

Top off evaporated water regularly — don’t let temps spike.

Harvest every few weeks to check growth and separate males if needed.
