Rainbow Trachyphyllia
A variant of Open brain coral (Trachyphyllia geoffroyi)

Representative Open brain coralphoto — a dedicated image of this exact morph isn't available yet.
The benchmark wild-collected Trachyphyllia morph: a single fleshy open-brain showing multiple bands of color at once — typically red, orange, green, and lime streaking out from the mouth like a folded ribbon.
📜 Backstory
"Rainbow Trachyphyllia" is the universal hobby trade name for multicolor wild colonies and is stocked under that exact label by Top Shelf Aquatics (TSA), Vivid Aquariums, Lucky Corals, Koral Kingdom, and LiveAquaria, among others. These are wild-collected from Indonesia and Australia, not aquacultured lines, so each piece is a unique one-off sold WYSIWYG. The color is natural pigment, not a named clone.
Keeper tips for this variant
Place on a soft sandbed (not rock) under low-to-moderate light (around 50-100 PAR) with very gentle flow; it inflates a large fleshy tissue mantle that can tear on sharp rock or get sandblasted by strong flow. Target-feed meaty foods at night.
