📜 Backstory
"Ultra Red" (Australia) and "Red & Green" (Indonesia) are standard wild-color trade descriptors used across vendors such as LiveAquaria and Aqua Imports. Trachyphyllia naturally occurs in red-and-green fluorescent mixes; these names describe the natural pigment grade of wild-collected pieces rather than any aquacultured lineage.
Keeper tips for this variant
Reds intensify under bluer spectrum and lower light; keep on the sandbed with soft flow to keep the heavy red tissue fully inflated. Spot-feed meaty foods occasionally.
