Hi Everyone It's been a long time waiting, but I finally have a small octopus! I picked the little fellow up from my LFS, who wasn't even sure of its locale. Please let me know what you think it might be. I BELIEVE it might be a dwarf, such as a mercatoris. Its active coloration is a reddish brown while its resting pattern is a mottled pale color. It has spent quite some time creating a little burrow underneath a piece of my live rock. Altogether, it is about 3-3.5" across (including arm span). The mantle appears to be about an inch or so long. I hope this helps. Thanks in Advance!
