I have been looking for a cool
macroalgae for the aquarium display portion and
THIS ONE has caught my eye before, but this website seems to be out of everything they sell, so I'm not sure if it's even in business anymore. Any way, they don't know what it's actually called so I can't run a search for it to find someone to buy it from.
It says it's very hardy. Also, for anyone knowing what it is, does it get eaten by herbivores in the tank, or do they leave it alone?
