I promised myself I would NOT jump into a new octo too soon. At the LFS where I got Al, they have an octo just like Al, hanging on the side of his critter keeper with arms curled tighter than my daughter's pigtails. My older daughter belted out, "Mom, you'd never get this guy, he's old, isn't he? Look at his arms!" At this the owner came over and some of the boys who work there to ask about this, as we now know more about octo keeping than them(thanks to Tonmo!). So they asked, is corkscrewing ALWAYS a sign of senescence or can it be signaling stress or poor H2O conditions? I admitted my ignorance and promised to post. For myself I want to know, what are the best signs of a healthy octo? As I troll the various LFS, what should I be looking for in a good specimen? Also, I've been keeping an eye on the online vendors, how can you trust that you'll get a healthy octo that way (maybe a Q for the "sources" page)?
