Key points when purchasing corals online. This guide explains how to identify healthy corals, how to choose reliable breeders, post-arrival acclimation procedures, and recommended purchase sets for beginners.
Coral husbandry is particularly deep within saltwater aquariums, and the sight of colorful corals blooming in a tank is truly breathtaking. However, when purchasing corals online, since you cannot physically examine them, worries linger like "What if the condition is poor?" and "Will acclimation fail?". This guide carefully explains everything you need to know when purchasing corals online, from selection methods to verification procedures to post-arrival care.

The most important thing when choosing corals for online purchase is discerning their health condition. Make maximum use of the information you can glean from photos and descriptions.
Polyps are extended: When polyps are fully extended, it's a sign of health. Individuals that are always closed are signs of stress or disease. Always check whether the polyps are extended in the photos.
Color is vibrant and uniform: Check for bleaching or unnatural brown discoloration. Bleaching is a sign of stress from light, water quality, and temperature combined, and recovery requires considerable effort.
Skeletal condition: For SPS corals (such as Acropora), it's important that the skeleton has no chips, corrosion, or algae growth. Skeletal loss may be damage during shipping, so check fine details in photos.
No excessive mucus secretion: Stressed corals secrete large amounts of mucus. If the water in the bag is milky white in post-arrival photos, caution is needed.
Additionally, before purchasing, it's reassuring to ask the breeder about their rearing environment (water temperature, salinity, pH, calcium, alkalinity and other water quality parameters, lighting used, water flow strength). The greater the difference from your own tank environment, the higher the difficulty of acclimation, so pre-confirmation is a shortcut to preventing failure.
Verification Points from Photos and Descriptions
In online shopping, photos and descriptions are essentially everything for purchase decisions. Keep the following points in mind when checking.
Photo Checklist Items
See through the lighting color: Under blue LED (actinic light), any coral appears to glow fluorescent. If possible, also check photos under white lighting to understand the actual color.
Are there photos from multiple angles?: Photos from the front, base, underside, and sides provide reassurance. It's important for not overlooking algae or corrosion at the base.
Frag and coral body size: "3cm frag size" and "3cm coral body" are completely different. Distinguish between the frag (base) and coral portion and verify the size notation carefully.
Freshness of shooting date: Products listed for a long time may not match the current condition with the photos. Check the shooting or update date, or request current condition photos from the breeder.
What to Confirm in Descriptions
Notation of difficulty level (soft coral, LPS, SPS)
Policies for DOA guarantee, refund for poor condition, or exchange
Packing method (insulation materials, oxygen filling presence or absence)
Available shipping seasons and temperature restrictions
If there are unclear points, use the messaging feature to ask the breeder directly. The speed and care of their responses are also a barometer of the breeder's trustworthiness.
Coral Types Recommended for Beginners
Corals vary greatly in difficulty depending on type. Rather than attempting difficult types from the start and failing repeatedly, starting with hardy types and getting the feel for coral husbandry is the key to sustaining the hobby. See also Beginner-Friendly Corals | 5 Top Recommendations.
Soft Coral (Beginner Level)
They're characterized by relatively high tolerance to water quality fluctuations and are easy to grow without intense lighting.
Star Polyps: Fast growth with abundant color variations including green and purple
Zoanthids: Adds vibrant color to the tank with easy propagation
Disc Coral (Hairy Disc): Flat shape makes it easy to incorporate into layouts
Toadstool Coral: Can grow large with impressive presence. White tentacles are beautiful
LPS (Intermediate Level)
While having a skeleton, they're relatively easy to keep, striking a good balance of beauty and hardiness.
Hammer Coral: Long tentacles sway gently, beautifully expressing water flow
Frogspawn Coral: Polyps extend during the day with striking presence
Skeletal corals represented by Acropora, where water quality management is extremely strict. Since they're high difficulty for beginners, I recommend gaining experience first with soft corals or LPS before attempting them. Acropora Care Guide provides detailed advanced management methods.
Post-Arrival Acclimation Procedure
Once your corals arrive, follow these steps without rushing. Careful acclimation makes a big difference in survival rate.
Unboxing and condition check: Unbox and check the coral's condition immediately upon arrival. Always take photos as this can serve as evidence in case of problems.
Temperature acclimation (approximately 30 minutes): Float the unopened bag in the tank and gradually match the water temperature. Sudden temperature changes cause significant damage to corals.
Water quality acclimation via drip method (1-2 hours): Using an air tube and valve, slowly add tank water to the bag—the drip method is safest. Corals are even more sensitive to water quality changes than fish, so taking time is essential.
Coral dipping (5-15 minutes): Soak in specialized coral dip solution (Coral RX, Revive, etc.) to remove parasites like flatworms, nudibranchs, and other pests. Skipping this risks parasites spreading throughout the tank, making it an essential step.
From temporary to permanent placement: Initially place in a location with gentle flow and not-too-intense lighting, and observe for 2-3 days. Once confirmed to be fine, gradually move to the intended location.
Br-Choku is a breeder-focused marketplace that directly connects breeders and buyers. Since no middlemen are involved, corals reach you in fresher condition.
Escrow payment for safe transactions: Instead of the buyer's payment being transferred to the breeder immediately, the system ensures payment only after the buyer confirms receipt. If the coral arrives in poor condition, appropriate resolution is guaranteed.
Breeder track record is clear at a glance: Transaction count, ratings, and review comments are public, making it easy to find trustworthy breeders. Real voices from actual purchasers are the most valuable reference for product selection.
Direct consultation via messaging feature: Before purchasing, you can ask breeders directly about water parameters and rearing environment concerns. Advice from knowledgeable breeders is the most reassuring support for beginners.
Quality from breeder-direct sales: Corals arriving directly from the breeder rather than through shops allow you to learn detailed information about care history, environment, and individual characteristics. For keeping your precious corals healthy long-term, please take full advantage of Br-Choku.
