Feeding approach
Use restrained feeding with small portions and record leftover feed to reduce water-quality pressure from overfeeding.
Weight management
Body weight is not a core metric; focus on body shape, swimming posture, feeding response, and schooling-behavior changes.
Immunization management
Immunization is not a routine priority; prioritize quarantine workflow, separate-tank observation, and new-fish introduction strategy records.
Parasite-control management
Parasite and bacterial treatment should be recorded together with water-change ratio, filtration maintenance, and temperature-stability logs.
Visit and recording advice
Common issues include white spot, fin rot, edema, and balance loss; record treatment concentration and a day-by-day change timeline.
Practical points
Recommended three-step maintenance baseline: daily behavior observation, weekly water maintenance, and monthly equipment review.
Breed breakdown (click for details)
Guppy
Height: about 3 to 6 cm
Weight: weight is not a routine indicator,focus on body condition and swimming posture
Lifespan: about 1.5 to 3 years
Eyes: Clear eyes with active food-chasing are baseline; isolation and fin-clamping should first trigger water-quality checks.
Betta
Height: about 5 to 7 cm
Weight: weight as a low-frequency reference,focus on fin extension and swimming stability
Lifespan: about 2 to 4 years
Eyes: Eyes should track normally; dull staring against glass requires assessment of temperature and stress.
Platy
Height: about 4 to 7 cm
Weight: weight is not a key metric,focus on body form and breeding status
Lifespan: about 2 to 4 years
Eyes: Eye-mouth coordination is a baseline check; increased surface gulping should first prompt dissolved-oxygen and water-quality review.
Molly
Height: about 6 to 10 cm
Weight: weight as a low-frequency reference,focus on body condition and abdominal changes
Lifespan: about 3 to 5 years
Eyes: Eyes should be bright and clear; cloudiness or protrusion often indicates infection or water-quality problems.
Zebrafish
Height: about 3 to 5 cm
Weight: weight is not a routine household metric,focus on schooling consistency
Lifespan: about 2 to 4 years
Eyes: Eye status and gill-cover movement rate are early health indicators.
