yeah teatime, i've had hermits all over it, red and blue legged, and i got an emerald crab, and it's still there. they seem to eat around it but not actually eat it. it does grow very slowly, like frank described. it doesn't bother me too much, i had hoped i could get enough of it to help with the trates a bit but seems like it's gonna take til next year to grow! it is a pretty sturdy plant whatever it is. i kinda like it, even though it's starting to kinda shade the areas below it. makes me wish i had bought more live rock out of that shipment when i had the chance.
