Schooling Bannerfish

The Schooling Bannerfish (Heniochus diphreutes) is one of the most reef-compatible butterflyfish relatives available in the marine aquarium hobby. Known for its elegant black and white vertical banding, elongated dorsal banner, and active schooling behavior, this species adds constant movement and striking contrast to larger reef and fish-only systems.

Unlike many butterflyfish species, Schooling Bannerfish are primarily planktivores and are generally considered reef safe in well-maintained aquariums. They thrive in stable marine systems with ample swimming space, moderate water movement, and a varied diet of high-quality frozen foods, pellets, zooplankton-based foods, and live foods.

Our conditioned and quarantined specimens undergo professional observation and proactive care protocols to help ensure healthy, stable fish ready for long-term aquarium success.

Dr. Mac’s Conditioned Fish Program

All of our conditioned saltwater fish undergo professional observation, quarantine, and proactive treatment protocols to help provide healthy, stable specimens for long-term reef aquarium success. Upon arrival we recommend floating each fish for 30 minutes to equalize temperature and then the fish should be released into your tank without additional acclimation.

The Pacific East Conditioning System

Every fish undergoes observation, conditioning
and proactive treatment before release

step-1_0ccf2c54-4a3e-4896-bdc4-89f238123f09

New arrivals are acclimated,
and inspected

step-2_400b411d-17ae-4476-b2bf-ca4214bf3432

We proactively treat fish during conditioning rather than simply holding them

step-3

Fish are closely monitored for feeding response, behavior and overall health.

step-4

Fish are transitioned onto prepared foods and conditioned for aquarium life.

Arrival and release dates help verify proper holding and conditioning time

"A properly conditioned fish adapts better, feeds more consistently, and has a stronger transition into aquarium life" - Dr. Mac

Every Fish is Evaluated to Ensure it Meets Our Health and Quality Standards

Order FAQs  

About Our Facility

Q: Are your corals aquacultured?
A: Yes. Many of our corals are grown in our Maryland Certified & Licensed Coral Aquaculture Facility.

Q: Why choose aquacultured corals?
A: Aquacultured corals are:
- More sustainable
- Better adapted to aquarium life
- Typically hardier than wild specimens

Q: Who selects and grows your corals?
A: Our corals are grown and curated by Dr. Mac a Board Certified Veterinary Pathologist with decades of hands-on reef experience.

Ordering & Shipping

Q: What does WYSIWYG mean?
A: “What You See Is What You Get.” The exact coral shown in the photo is the one you will receive.

Q: Can I request a specific color or variation?
A: For WYSIWYG items, what’s pictured is what you get. For non-WYSIWYG items, we do our best to match color and size, but natural variation occurs.

Q: Can I combine multiple orders to save on shipping?
A: Yes—contact us before shipping and we’ll consolidate when possible.

Q: How are corals and fish shipped safely?
A: We use insulated boxes, temperature control (heat/cold packs), and overnight delivery to ensure safe arrival.

Q: What days do you ship?
A: Typically Monday–Wednesday to avoid weekend delays.

Q: Do I need to be home for delivery?
A: Yes—someone should be available to receive livestock immediately.

Q: What if my coral or fish arrives dead (DOA)?
A: Contact us within a specified timeframe (e.g., 2 hours) with clear photos, and we will resolve it quickly.

Q: What voids the guarantee?
A: Missed deliveries, improper acclimation, or delays beyond our control.

Live Arrival Guarantee

Q: What if my coral or fish arrives dead (DOA)?
A: Contact us within a specified timeframe (e.g., 2 hours) with clear photos, and we will resolve it quickly.

Q: What voids the guarantee?
A: Missed deliveries, improper acclimation, or delays beyond our control.

Acclimation & First 24 Hours

Q: How do I acclimate new livestock?
A: Float to match temperature, then drip acclimate before placing in tank.

Q: Should I dip corals before adding them?
A: Yes but be careful, coral dips help prevent pests but use caution. Certain corals might benefit from a short quarantine period instead of a dip so as to further stressing them.

Q: Why does my coral look closed or stressed?
A: This is normal after shipping—most corals open within 24–72 hours.

Aquarium Setup & Compatibility

Q: Where should I place my coral in the tank?
A: Placement depends on the coral type (LPS, SPS, soft). Lighting and flow requirements vary—check each product description.

Q: Can different corals touch each other?
A: Many corals have sweeper tentacles and can sting neighbors. Always allow space.

Q: How fast will my coral grow?
A: Growth depends on species, lighting, water quality, and feeding.
