Kole Tang Starter Care Guide
A practical introduction to kole tang care, including health risks, water quality, tank setup, food and behaviour.
Use this guide to notice and organize information. Contact a qualified veterinarian for medical concerns or urgent change.
About the Kole Tang
Kole tangs are bristletooth surgeonfish that spend the day rasping fine algae and organic film from rock and glass. They stay smaller than some tangs, but they are still active swimmers that need a large mature aquarium.
A sharp scalpel-like structure sits near the tail and can injure people or other fish during handling and territorial fights.
Health risks to know about
Important concerns include marine parasites, poor body condition, nutritional imbalance, lateral-line or skin problems, ammonia or nitrite poisoning and aggression injuries.
Rapid breathing, repeated scratching, white spots, a pinched belly, skin erosion or refusing food needs prompt attention.
Tank, water and equipment
Use a large, long, mature marine aquarium with strong filtration, high oxygen, stable rockwork, open swimming space and established grazing surfaces.
Measure salinity with a calibrated refractometer. Do not add the fish solely to clean algae, and do not scrub every grazing surface spotless.
Food and feeding
Offer marine algae sheets, a complete herbivore-focused marine food and suitable small meaty foods for variety.
Watch body condition and provide regular feeding even when the fish spends all day grazing.
Behaviour, tank mates and enrichment
Steady rock grazing and active laps are normal. The mouth may leave visible rasp marks on algae films.
Kole tangs are generally reef compatible, but they may become territorial toward similar tangs or other grazing fish.
When to contact an aquatic veterinarian
Get help for gasping, collapse, severe wounds, major swelling, inability to stay upright, rapid unexplained deaths or a problem that continues after water parameters are corrected.
Test ammonia, nitrite, nitrate, pH, temperature and salinity whenever behaviour changes. Water quality is part of the medical history, so record results before contacting an aquatic veterinarian.
