Common five-banded barb problems
- Hard, alkaline water and high nitrate wear them down; soft water and regular changes keep them colorful.
- Fish sold under this name are often the six-banded barb, a close relative with the same care.
Test the water first whenever fish look unwell: see what your readings mean, then match the symptom. For disease, a vet who treats fish can diagnose it and advise treatment.
