Building a vibrant reef aquarium is a journey that often leads hobbyists to seek out rare and high-quality coral specimens. These unique pieces serve as the focal point of a saltwater tank, offering colors and growth patterns that are not found in standard varieties. Finding these corals requires a combination of patience, research, and knowing how to evaluate the health of a specimen before making a purchase.
Whether you are a seasoned reefer or a beginner looking to add your first premium piece, understanding what makes a coral high-quality is essential. This guide will walk you through the process of identifying rare corals, choosing reliable sources, and ensuring your new additions thrive in their new environment.
Understanding What Makes Corals Rare
In the reef-keeping hobby, rarity is often defined by a combination of color, growth rate, and availability. Some corals are rare because they are difficult to collect from the wild, while others are rare because they grow very slowly in captivity. Understanding these factors helps you appreciate the value of the specimens you find.
Vibrant and Unique Coloration
The most sought-after corals often feature “ultra” or “rainbow” coloration. This means the coral displays multiple high-contrast colors under actinic lighting. For example, a standard Torch coral might be green, but a rare specimen could feature gold, purple, and tipped tentacles that glow intensely.
Specific Growth Forms
Sometimes, the way a coral grows makes it rare. Certain Acropora species have specific branching patterns that are highly prized. When a coral develops a consistent, aesthetically pleasing shape that is difficult to replicate, it becomes a high-end collector’s item.
How to Identify High-Quality Specimens
When you are looking to buy premium corals, you must look past the color and evaluate the actual health of the animal. A beautiful coral that is stressed or diseased will not last long in your tank. Follow these steps to ensure you are buying a healthy specimen.
- Check for Polyp Extension: Healthy corals should have their polyps extended, especially in species like SPS (Small Polyp Stony) and LPS (Large Polyp Stony) corals. This is a sign that the coral is feeding and comfortable in its current water parameters.
- Inspect the Tissue: Look closely at the base of the coral. The tissue should be thick and cover the skeleton entirely. If you see white skeleton showing through or tissue peeling away, the coral is likely stressed or dying.
- Look for Pests: High-quality sellers take great care to keep their tanks pest-free. However, you should always check for flatworms, red bugs, or nudibranchs. These pests can quickly infest your entire aquarium if introduced on a new frag.
- Verify Color Stability: Some corals are “filtered” in photos to look more vibrant than they actually are. When possible, ask to see the coral under standard white light to ensure its natural colors are still impressive.
Where to Find Premium Corals
Finding rare specimens often requires looking beyond your local general pet store. Specialized vendors and hobbyist communities are usually the best places to find high-end livestock.
Specialized Local Fish Stores
Some local fish stores (LFS) specialize specifically in saltwater reefs. These shops often have dedicated “show tanks” where they keep their most prized specimens. Visiting in person allows you to see the coral’s health firsthand and discuss its specific care requirements with the staff.
Online Boutique Vendors
The internet has made it easier than ever to find rare corals from across the country. Many high-end vendors offer “WYSIWYG” (What You See Is What You Get) listings. This means the photo you see on the website is the exact coral frag you will receive. This is the preferred way to buy rare corals online, as it eliminates surprises regarding color or size.
Frag Swaps and Shows
Coral shows and local frag swaps are excellent venues for finding rare pieces. Hobbyists and professional growers gather to trade and sell specimens that they have grown in their own systems. These events are great because the corals are often already acclimated to captive conditions, making them hardier than wild-caught pieces.
Key Questions to Ask the Seller
Before finalizing a purchase, especially for an expensive or rare piece, you should ask the seller a few specific questions. This information will help you prepare your tank for the new arrival.
- What are your current water parameters? Knowing the alkalinity, calcium, and nitrate levels the coral is used to will help you acclimate it more effectively.
- What lighting is the coral under? If the coral is used to high-intensity LED lighting and you place it under low-light T5 bulbs, it may lose its color or fail to grow.
- Is it aquacultured or wild-caught? Aquacultured corals (grown in tanks) are generally much hardier and more likely to survive the transition to your home aquarium than those taken directly from the ocean.
- What is your shipping and DOA policy? If buying online, ensure the seller offers a “Dead on Arrival” guarantee. Reliable sellers will provide a refund or replacement if the coral does not survive the trip.
Preparing for Your New Arrival
Once you have found the perfect specimen, you need to ensure your tank is ready. Rare corals often require very stable conditions to maintain their vibrant colors and growth rates.
Stability is Key
Most high-end corals, particularly SPS varieties, do not react well to fluctuations in water chemistry. Ensure your alkalinity and salinity are stable for at least two weeks before adding an expensive new piece. Using an automated dosing system or an auto-top-off (ATO) can help maintain this consistency.
Acclimation and Dipping
When your coral arrives, never skip the dipping process. Use a specialized coral dip to remove any hitchhikers or pests that might be hiding on the frag plug. After dipping, slowly acclimate the coral to your tank’s light by placing it on the sand bed for a few days before moving it to its permanent location on the rockwork.
Conclusion
Finding and purchasing rare live corals is an exciting way to enhance the beauty of your saltwater reef aquarium. By focusing on health indicators, choosing reputable sellers, and asking the right questions about care and origin, you can successfully add stunning specimens to your collection. Remember that the key to keeping these beautiful animals alive is providing a stable environment and proper nutrition.
