Pics a little fuzzy but may be a macroalgae known as mermaids wine glass
I don’t think that’s it , they don’t really have a stem ; and if I take my tweezers they can be scraped off the rocks . Here’s a picture of them in the tank, almost flower like looking ?Pics a little fuzzy but may be a macroalgae known as mermaids wine glass
AgreeThere are stemless (mermaid) wine glasses
Super interesting! I doubt they are harmful. Calcified macros aren't the fastest growers like Caulerpa. Adding that to my list of macros to look out for!I was able to find what they are , still no clue if they’re harmful though?
Thank you so much I’m going to do a calcium check and see if my levels are higher than usual I really appreciate it!I’d guess that - at worst - it could turn invasive and leave you needing to find a way to remove it, but it reportedly typically doesn’t last long in aquariums:
Edit: Just to add, the site lists it as a good species; generally those species are fine and don’t cause problems, but occasionally (like the Neomeris sp. listed on the site) they become highly invasive in someone’s tank - it’s rare, but it does happen. So, I’d guess the algae will be fine for you, but you never know until it plays out in real time.Section: Algae (Green): Group: Calcareous Algae: Species: Parvocaulis parvulus (Umbrella Alga, Parasol Alga)
