After 9 months, I lost my A. aculeatus, "Leggs" RIP. Now I just received a TINY Atlantic long leg octo from Foxy Tropicals. He or she, haven't determined yet. I have a brittle star that is twice as big as this new one, in the tank, and wonder if I should remove it?? Here is a photo of the new octo.I just noticed that he has a forked arm at the end. I will try to get a pic.
