📜 Backstory
"Master Grade" / "Master" is the hobby's top-tier descriptor for the very best rainbow Trachys, documented in Reef2Reef threads (e.g. the "Master Grade Rainbow Trachyphyllia" and "Trachyphyllia sp. rainbow master grade" threads) and used by vendors such as Vivid Aquariums and European importers, where showpieces can run from roughly $1,000 to €2,000. It mirrors the "Master Scoly" grading culture. These are wild-collected one-offs; there is no single owner-named lineage.
Keeper tips for this variant
Give it open sandbed real estate so the fully inflated mantle can expand; keep flow indirect and feed small meaty foods at night to maintain the heavy tissue and color. Moderate, blue-leaning light preserves contrast.
