The Bluelined Snapper (Bluestripe) is a bright yellow fish with 3–4 thin, electric-blue lines running along its sides. Kids love it because it looks like a tiny yellow submarine with blue racing stripes. It is popular in reefs and big marine aquariums because it is colorful and often swims in groups.

Bluelined Snapper Origin

  1. Lives across the Indo-Pacific: from the Red Sea and East Africa through Indonesia to the central Pacific and Australia.
  2. It sometimes forms big schools around reefs, caves, or wrecks.

Temperament

  1. Usually schooling and peaceful with its own kind, but can be bold or eat very small animals
  2. It is not a shy fish and will swim actively during the day
  3. When kept alone or in a small tank, it may show more chasing or nipping

Compatibility

  1. Gets along with other medium-to-large, robust reef fish (groupers, larger wrasses) if the tank is large and there is space.
  2. Avoid very small gobies, shrimp, or tiny ornamental crabs — they can become snacks. Also, be careful with very timid species.

Bluelined Snapper Price

  1. Imported marine fish prices vary by size and supplier
  2. You can expect roughly ₹6,000 to ₹12,000 for a healthy medium-sized specimen in India
  3. Smaller juveniles cost less, large adults cost more

Bluelined Snapper Habitat requirements

Initial Setup Cost

₹10,000 - ₹30,000

Water Temperature

24º -28ºC

Water Type

Salt Water

PH Level

8.1 - 8.4

Tank type

  1. Saltwater (marine) aquarium only. Not for freshwater or simple reef tanks with delicate corals.

Bluelined Snapper Aquarium size

  1. Minimum 200 gallons (≈750 L) recommended for an adult or a small group—these fish like to swim and school. Smaller tanks stress them.

Water conditions

  1. Temperature: 24–28°C (75–78°F)
  2. pH: 8.0–8.4
  3. Hardness / Salinity: Normal marine salinity around 1.023–1.025 (specific gravity); moderate hardness

Bluelined Snapper Environment needs

  1. Plenty of open swimming space plus rockwork, caves, and ledges where they can shelter or school.
  2. Moderate lighting; lots of hiding spots help reduce chasing. Avoid keeping with tiny invertebrates you want to protect (shrimp, small crabs).

Bluelined Snapper Nutritional Guide

Avg Monthly Expenses

₹200 - ₹ 300

Diet type

Carnivore/opportunistic omnivore — mainly meat-based

Suitable foods

  1. Frozen or fresh meaty foods such as:
  2. Shrimp
  3. Crabs
  4. Stomatopods
  5. Cephalopods
  6. Planktonic crustaceans
  7. High-quality marine pellets
  8. Flakes designed for carnivores
  9. Occasional algae or mixed foods are fine, but protein is key.

Feeding Frequency & Tips

  1. Feed 1–2 times a day for adults
  2. Juveniles may eat more often in smaller portions
  3. Offer varied foods (pellets + frozen meaty items) to keep color and health strong
  4. Remove uneaten food after a few minutes to keep the water clean

Bluelined Snapper common health issues

Marine Ich

Marine Ich appears as small white grains (like salt) on the skin and fins of infected fish. Symptoms include scratching, labored breathing, hiding, or loss of appetite, typically treated by quarantine and treatment with either a copper-based medication or hyposalinity in a separate tank, both of which kill free-swimming life stages. Treatments need to cover the entire life cycle. Keeping water quality high avoids copper toxicity, and good water quality and quarantine can help prevent outbreaks.

Marine Velvet

Velvet gives fish a dusty look, rapid breathing, clamped fins, and lethargy. It spreads rapidly and can be fatal. The most common treatments are formalin baths and anti-parasitic dips, although these must be done in a timely manner. Quarantine and water quality improvement are also important. As many treatments affect invertebrates, a sick fish should be treated in a separate tank.

External flukes and other parasites

External flukes attach onto the gills or skin, causing redness, respiratory distress, and rubbing. Gasping at the surface and poor color can also signal sickness. Treatment could include praziquantel or medicated baths. Dosing instructions should be followed; re-dosing may be required for some medications, and fish may need to be held in quarantine. Good water and food may help recovery.

Bacterial infections

Bacterial infections are uncommon, often following injury or stress (scrapes, poor water). Fish have red sores in addition to torn fins or white patches. Doctors treat the issue through antibiotics. They also control topical wounds and improve water quality. Early detection and maintenance of a clean, stress-free aquarium environment are the best preventative measures.

Bluelined Snapper General Health Tips

  1. Quarantine all new fish for 2–4 weeks and treat preventively
  2. Keep water stable and perform regular water changes
  3. Feed a varied, protein-rich diet and avoid overstocking
  4. Observe fish daily for changes in color, appetite, or behavior
