Macroalgae For Marine Reef Aquariums: Halimeda Opuntia ecosystems

Halimeda opuntia

A unique form of calcareous algae that features tight, segmented discs, found attached to rocks, sandy bottom and other algae. This particular species does not possess a rhizome as other species of halimeda, but is an encrusting variety that spreads both laterally and horizontally. These are hardy specimens collected from the Caribbean, that do very well in tanks with high calcium levels such as reef aquaria. We ship several clusters approx 3"- 4" in diameter. This species will often appear white or pale when received, but will return to the bright green coloration within a few days.
