Common striped Raphael catfish problems
- Do not catch them with a net: their fin spines lock out and tangle; use a container.
- Very small fish may be eaten at night.
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.
