Hey, new to the club but I have a question. At the most recent meeting I won an sps frag. It looks like an acro, green with a hint of blue at the tips. The cup said blue....the rest was not legible. I think this guy is a bit aggressive. At night it will send out these long mucous like strands. Not every night, but only at night and theY remain attached to the poly end. I do not believe them to be tentacles, but I do believe they are mucous and nematocysts laced. Are sps acro like corals aggressive? I have kept it away from any others. Really not willing to sacrifice another for my curiosity. Well if anyone has some input let me know...and if you know what the coral is/was that would be great to. Thanks. Pete
