About the Bala Shark
Bala sharks, also called silver sharks, are not true sharks. They are large, fast schooling fish that can grow beyond 30 centimetres and need a group as well as a very long aquarium.
The small silver juvenile sold in stores is a classic tankbuster. Buying one with plans to upgrade later often leaves the fish without suitable adult housing.
Health risks to know about
Important concerns include ammonia or nitrite poisoning, injuries from panicked collisions or jumping, parasites, bacterial disease, poor nutrition and chronic stress from small groups or cramped housing.
Gasping, nose damage, clamped fins, sores, rapid weight loss, abnormal swimming or repeated frantic dashing needs prompt investigation.
Tank, water and equipment
Use a very large, long, fully cycled and heated aquarium with strong filtration, open swimming room, a secure lid and carefully placed smooth decor.
Plan for a substantial adult school before purchase. Sudden light, vibration or movement can startle these skittish fish.
Food and feeding
Offer a complete omnivore food sized for the fish, with suitable frozen, live and plant-based variety.
Distribute food across the group and adjust portions as juveniles grow.
Behaviour, tank mates and enrichment
Fast schooling and sudden group turns are normal. Repeated crashing, hiding or frantic pacing suggests stress.
Choose robust peaceful tank mates that cannot be swallowed and will not compete with the school's swimming space.
When to contact an aquatic veterinarian
Get help for gasping, collapse, severe wounds, major swelling, inability to stay upright, rapid unexplained deaths or a problem that continues after water parameters are corrected.
Test ammonia, nitrite, nitrate, pH, temperature whenever behaviour changes. Water quality is part of the medical history, so record results before contacting an aquatic veterinarian.
