I have a "ton" of them my tank(mini-carpet anemone's - they look exactly like the photo noodleman posted),
beware They multiply like crazy and are very invassive. They dont harm anything but boy if your bare arm brushes up against them you'll get burning welts that last a week!
If only I can figure out how to get them off my large rocks without damanging them?
I have so many I was actually thinking of using Kalc to kill some..But am afraid they might pollute my tank when (if) they die from it.
Thanks Chris but this rock is Super large, c shaped, tonga kalini it's one of my favorites. did you ever think you'll ever have a favorite rock
the pictures aren't the best but what more can i say... I started out with two last yr and I have about 60 now.. also I just finished cleaning the front glass and there is sand blowing around not the best time to take a picture i guess.
