Wow! I've got a red with black stripes one. Is it going to get that huge? I've it a year now and I has double in size already. I only ever see its arms though.
Waiting by the anemone, careful! lol. I had a brittle star, all black, come in as a hitcher. My first real marine aquatic life. Then about six months later, wife comes in to check on the anemone, turns out light, brittle star makes a dash, right into the LT and that was that. I was so sad, wife enjoyed the show regarding how cool it was. She told me to cheer up and that it was nature. My friend knew I was so sad about that loss, that she caught a brittle star for me down in Izu. Thats the red and black I mentioned earlier.
