Appearance and identification

Compared with the finely barred G. zebrinus, it has sparser body markings and different tail colours.

Floor and movement space

Use at least 20 gallons.

Aquarium environment

Prioritise clean, oxygen-rich moving water and smooth grazing stones. Planting must leave these usable; it suits flowing water, not an ordinary still-water planted tank.
