Aquarium Fish

Disk Tetra

The Disk Tetra (Myleus schomburgkii) can attain a very large size as adults, reaching up to 16 inches (42 cm)! You need a very large tank if you plan on keeping the Disk Tetra.

These Disk Tetras are known to have a strong bite (ref: fishbase - "Has powerful dentition that can cause serious bites.") so use caution when working around larger adults.

Most hobbyists should just take a pass on this fish if you see them in the store given their potential adult size.
