Can Bala Shark Live With Iridescent Shark?
Yes, bala sharks and iridescent sharks coexist well in 300 gallons or larger with identical water parameters and matching activity levels.
Why
- Both species grow to similar adult sizes, with bala sharks reaching about 12 inches and iridescent sharks reaching 12-18 inches, so neither will prey on the other.
- Both species tolerate the same temperature range of 72-82F and pH range of 6.5-7.5, making water chemistry simple to manage.
- Both are active, peaceful fish that prefer swimming space over decorations, and they rarely interact aggressively with fish of similar size.
- Both species are schooling fish by nature and do better in pairs or small groups, so keeping both together satisfies their social needs.
- A 300-gallon tank provides the open swimming space that both species need to thrive and display natural behavior.
What could go wrong
Both species are large and produce heavy bioload, so exceptional filtration and large weekly water changes of 30-40 percent are necessary to maintain water quality.
