Bought it just as an encrusted plug for a couple of bucks but the last couple of months is showed excellent growth and beautifull coloration with bright blue tips. The pictures don't do it justice, but hope somebody can tell me the name of this species.
Looks close to a secale to me but the round long tips are throwing me off a little. But I do see that when flow and light is off or on the sides of some wild colonies.
