Conditioning before the ring
Generations ago, Siamese fighting fish were kept for contests. Experienced keepers developed conditioning routines in much the same way that a boxer prepares before entering the ring: building stamina, alertness, confidence, and the ability to remain composed in unfamiliar surroundings.
These methods belong to Thailand's living betta heritage. The account below is translated and adapted from a Thai keeper's text for historical and educational study.
Selecting a sound fish
At approximately six to eight months old, each fish was moved from its rearing vessel into a clear jar so the keeper could assess body condition, structure, scales, skin, and overall vigor.
Selected fish were then rested for 10–15 days in conditioned water prepared with dried Namwa banana leaves. Overweight fish were fed on alternate days during this period. The traditional goal was a balanced body, tight scales, and a smooth, healthy sheen before any further conditioning began.
Controlled chase conditioning
The routine known as luk lai, literally “chase fish,” used a wide-mouthed jar for safe handling. Five or six young females, about three to four months old, were placed inside early in the morning.
The male was first allowed a brief visual display of roughly one minute. He was then introduced to the wider vessel and allowed to swim after the smaller fish for about 30 minutes under constant observation. The purpose was sustained movement and swimming strength—not contact or injury.
A brief, watched encounter
Another traditional exercise presented a large female that had been rested for four or five days. When placed together, the fish displayed and circled one another. The session lasted only three to five minutes and required continuous supervision.
The keeper prevented all biting. A frightened or injured female would no longer display naturally, defeating the purpose of the exercise. Afterward, the male rested in his jar, was fed, and moved to a quiet sleeping vessel at around 6 p.m. The cycle was traditionally repeated for 10–12 days.
Movement, balance, and composure
Old conditioning systems varied by household and region. The most useful ideas can be understood today as low-stress exercise and acclimation—never as a reason to force a fish beyond its limits.
Target movement
Some keepers encouraged a short upward movement toward a suspended target. Any modern version should be brief, reward-based, and free from sharp or harmful objects.
Gentle current
Swimming against a mild current was used to build stamina. Strong swirling water can disorient a betta and cause injury, so the fish's balance and breathing must guide the session.
Ploi acclimation
Frequent, calm changes between jars of different shapes helped fish become less startled by new containers and sudden environmental changes. Familiarity created composure.
Confidence comes from familiarity
Even a bold betta can startle when suddenly netted, exposed to bright light, or moved into a new vessel. Traditional keepers called the acclimation practice ploi: calmly varying jars and surroundings so the fish learned to settle quickly instead of panicking.
The enduring lesson is not aggression. It is attentive observation. Good keepers read posture, breathing, balance, color, and recovery—and stop whenever the fish shows stress.

Preserve the knowledge. Protect the fish.
Thai betta culture is built on close observation, patience, and generations of practical knowledge. Its future depends on carrying that heritage forward with modern standards of care.
