Can Oscar Live With Tinfoil Barb?
Yes, Oscars and Tinfoil Barbs coexist in 75 gallons or larger, and the barb stays large enough to avoid becoming prey.
Why
- Tinfoil Barbs reach 14 inches. Oscars reach 12-14 inches. The barb does not fit easily in the oscar's mouth.
- Temperature overlap 74-77°F suits both species.
- pH 6.5-7.5 covers both. Neither needs soft or hard water specifically.
- Tinfoil Barbs are active swimmers that stay in the middle and upper levels, while Oscars occupy the mid-level.
What could go wrong
Tinfoil Barbs need long horizontal swimming space. A 75-gallon tank with heavy decor reduces usable length and causes the barbs to bump the glass repeatedly.
