There is alot of info in the forum already about this so i apologize in advanced. :deadhorse: There seems to be just so much vary opinion regarding these stars that I want the most recent information/experience as possible. Can anyone describe in a nutshell the difference between the two. I read the major difference is the amount/size of the spines on the legs. Also wanted to know temperament of the 2, with the exception of the green brittle star which is a known exception. I have a tank with both of them mixed together and I want to add them to other tanks but don't want to do anything stupid.
