Orange Stripe Bristletooth Tang
Ctenochaetus striatus
Fine wavy blue lines cross an olive-brown body, with small orange spots on the head. This large bristletooth browses fine material from established surfaces and needs room, compatible tank mates and a reliable supplemental diet.
Care recommendations differ between suppliers; Fish Match uses the more spacious 180-gallon recommendation for planning this larger bristletooth.

+ Why you’ll love them
- Fine wavy blue lines cross an olive-brown body, with small orange spots on the head.
- Browses algal films on established surfaces.
- Generally compatible with corals when appropriately housed.
! Things to consider
- Needs adult-sized housing: plan for 180 US gallons or more with suitable swimming space.
- Care recommendations differ between suppliers; Fish Match uses the more spacious 180-gallon recommendation for planning this larger bristletooth.
- Requires a consistent feeding routine and stable water.
- Has sharp tail spines; handle carefully.
Tank and habitat
- Recommended volume
- 180 US gallons or larger; allow for stocking and layout.
- Full-grown size
- 10 inches (maximum adult size)
- Tank footprint and swimming space
- Choose a long rectangular aquarium with open swimming lanes and room to turn. Leave space around rockwork; a tall narrow tank is a poor substitute for swimming length.
- Tank maturity
-
6 months recommended
Use an established, fully cycled aquarium with stable filtration and productive grazing surfaces. Confirm water stability and reliable feeding access before introduction. Suggested tank age is a planning guide, not proof of readiness. Complete cycling, stable water and the right food supply are essential. - Habitat and equipment
- Provide good circulation and gas exchange. Arrange secure rockwork for shelter and grazing, keep open water available, and use a secure lid. Take care around the sharp tail spines.
Care and compatibility
- Temperament
- Semi-aggressive / territorial
- Why this care level
- Care recommendations differ between suppliers; Fish Match uses the more spacious 180-gallon recommendation for planning this larger bristletooth.
- Suitable tank mates and conflicts
- Choose tank mates that allow uninterrupted browsing and feeding. Other bristletooth tangs and established territorial surgeonfish can cause persistent disputes.
- Alone, pair or group
- A single tang is the simpler plan. Keeping several requires additional space, individual assessment and a way to separate incompatible fish; wild groups do not establish an aquarium stocking rule.
Corals and invertebrates
- Coral safety
-
Generally compatible
Generally compatible with corals, but observe the individual. Algae grazing should not be mistaken for a guarantee that no picking will occur. - Shrimp safety
-
Generally compatible
Generally compatible with ornamental shrimp; monitor introductions and individual behavior. - Snail safety
-
Generally compatible
Generally compatible with snails. Continue observing grazing behavior around small invertebrates. - Clam safety
-
With caution
Use caution around clam mantles: surface browsing can lead to unwanted picking. Observe closely and separate if persistent irritation occurs.
Food and feeding
- Diet
- Herbivore / surface browser; algal films and prepared foods
- Feeding plan
- Provide mature surfaces for browsing fine detritus and algal material, supplemented with appropriate prepared foods. Offer food consistently and check body condition; natural grazing is a supplement, not a complete feeding plan.
- Prepared or live food
- Try small herbivore pellets, spirulina-rich preparations, marine algae and suitable frozen foods. Ask what the individual already eats; acceptance varies.
Water conditions
- Temperature
- 72–78 °F (22–26 °C) is a commonly published aquarium reference range. Maintain stable conditions and consider the needs of the whole community.
- Specific gravity
- Specific gravity 1.020–1.025 appears in common species-care guidance. Match the needs of corals and other inhabitants, and avoid abrupt changes.
- pH
- pH 8.1–8.4 is the published marine aquarium reference range used here; maintain stability rather than chasing a single reading.
Long-term care
- Lifespan
- The linked references do not establish a reliable typical captive lifespan for this profile. Plan for long-term care and maintain a realistic adult housing commitment.
- Growth and future planning
- Adults may reach about 10 inches. Growth depends on the individual and conditions; juvenile purchase size should not determine the long-term aquarium.
Before you buy
- Is this fish right for your tank?
- Check identification and adult space; orange-stripe common names alone can be ambiguous.
- Buying checklist
- Ask to see the fish eat. Look for a well-filled body, clear eyes, intact fins and normal swimming and breathing. Plan quarantine and confirm the seller’s species identification and feeding routine.
