Description and Care

The Gold Stripe Maroon Clownfish (Amphiprion biaculeatus) is a striking Indo-West Pacific anemonefish recognized for its rich red to maroon coloration and three contrasting light-colored body bands. The Gold Stripe form develops distinctive yellow to golden coloration within these bands, creating a dramatic contrast against the deep maroon body.

One of the most noticeable characteristics of Amphiprion biaculeatus is the substantial size difference between the sexes. In an established pair, the female is considerably larger than the male, a difference clearly represented by this pair. FishBase documents this characteristic in wild pairs and records a maximum species size of approximately 17 cm (6.7 inches) total length. FishBase

The species is naturally distributed through the Indo-West Pacific, including Indonesia, the Philippines, New Guinea, the Solomon Islands, Vanuatu and northern Australia. Adults inhabit lagoon and seaward reef environments, particularly protected coastal waters and lagoons. FishBase

In nature, A. biaculeatus has a close relationship with sea anemones and is documented in association with the Bubble Tip Anemone (Entacmaea quadricolor). An anemone is not required to maintain the species in an aquarium, however, provided the fish have appropriate shelter and suitable aquarium conditions. FishBase

Gold Stripe Maroon Clownfish are bold, territorial fish, particularly once an established pair claims an area of the aquarium. Their combination of deep coloration, distinctive gold bands and dramatic difference in male and female size makes a mature pair especially impressive.

This pair is wild collected from Indonesia and is offered as part of Dr. Mac’s Quarantined and Conditioned Fish.

Aquarium Requirements: Provide substantial rockwork with sheltered areas and enough space for the pair to establish a territory. Because mature Maroon Clownfish can be strongly territorial, aquarium layout and tankmate selection become increasingly important as the fish mature.

Temperament: Maroon Clownfish are among the more assertive clownfish. An established pair may vigorously defend its chosen territory, particularly around a host anemone or favored area of rockwork. The larger female can be especially territorial. Tankmates should therefore be selected with the pair's adult behavior and size in mind.

Reef Compatibility: Reef compatible. Amphiprion biaculeatus is naturally reef-associated and is not a coral predator. Its principal aquarium compatibility consideration is territorial behavior rather than coral predation.

Diet and Feeding: In nature, A. biaculeatus feeds primarily on zooplankton and benthic algae. In the aquarium, offer a varied diet incorporating quality marine pellets or flakes, mysis shrimp, enriched brine shrimp, finely chopped marine foods and other appropriately sized foods.

Anemone Association: FishBase documents A. biaculeatus in association with Entacmaea quadricolor, the Bubble Tip Anemone. A host anemone can encourage natural behavior but is not required for successful aquarium maintenance. FishBase

Pair Behavior: Maroon Clownfish form distinct pairs, with the female becoming considerably larger than her male partner. The species is egg-laying; eggs adhere to the substrate and the male guards and aerates them during development. FishBase

The Pacific East Conditioning System

Every fish undergoes observation, conditioning
and proactive treatment before release

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

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.

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.
