Low light & low flow. Otherwise they bleach out & shrivel up. They are like most red corals. Just talked to TomR & Chin about blastos & how they did poorly under high light & Chin's only thrived once it was in a cave.
I had those other types of blastos that grow on long stalks but they were green in colour & did fine under MH. Perhaps its the colour & species variety that is creating the confusion. (just like how green open brains like light & red ones don't).
