Can Iridescent Shark Live With Tinfoil Barb?
Yes, iridescent sharks and tinfoil barbs coexist well, though this pairing requires an enormous tank of at least 300 gallons due to the size of both species.
Why
- Iridescent sharks grow to 12-14 inches and need swimming space, while tinfoil barbs reach 10-12 inches and occupy similar mid-water levels.
- Both species tolerate the same temperature range of 72-77F and pH of 6.5-7.5 without stress.
- Neither species is aggressive. Tinfoil barbs are peaceful schooling fish and iridescent sharks are skittish but not predatory.
- A 300-gallon tank provides enough horizontal swimming space for both large species to coexist without competing for territory.
What could go wrong
Both species grow very large and produce heavy bioload, so filtration must be extremely hardy to handle the combined waste in a smaller-than-ideal setup.
