Hi there, im new to the husbandry as of today, April 18. Although ive been reading acticles for almost a month now, my local pet store finally had an octo. the only thing that is wrong is that they and I did not know what kind it was. I know it is very difficult to tell, but i'm gonna give it a try any ways. It has a mantle langth of about an inch with an overall lebgth of about 8 inches. Although ive only had it for about 4 hours, It's most common color seems to be a cream or it is clear, which is normal, but it has alot of lite, but shiney green specles all over it. As soon as i put it in the tank is started to cruise around looking in holes for food and didnt even care about hiding like most new octo's. It seems to not be bothered by light at all. I even stuck my hand in the tank and dropped a baby crab infront of it which it ate immediately. I'm gonna take a stab and say it's a vulgaris, but who knows. I'm kinda shopcked by how cool it's acting so if anyone can share some info that would be great. I will have pics shortly after it comes out from feeding later.
