I just wonder on her size as she still is very small for a Briarius. Maybe has doubled in size. I have not seen the dilated pupil since that one time. She's active but very secretive but that could be cause her playmate was away for a week!
RIP Inkler....I found her yesterday morning gone...Remember a few octopuses back I questioned the growth rate and wondered if sometimes we acquire the ones that would not make it in the wild, but because we have them in a safe environment they live longer than they would have? I think this was the case with Inkler. She never grew to the size a Briarieus should be. Her size was , curled up, the size of silver dollar. I noticed she had stopped eating about a week or so ago and was doing that pacing that they do with the enlarged pupils. Water quality is fine.
Size has been a large varient in the briareus but Inkler was by far the smallest. It may be that she/he was much older (thus no sign of huge growth rates) and was much older than assumed. Until this one, I have thought that briareus was one of the few we could use size to gauge age.
