I am a science teacher and keep a bunch of tanks in my room, a 40 gallon reef, 75 gallon FO, 55 gallon fresh and a 29 gallon QT tank. I have wanted an octopus for awhile and have done quite a bit of research on octos. I went to the fish store yesterday to buy something for the FO tank. They didnt have anything I was looking for but they did have a small, golf ball sized Octopus Vulgaris. At least it appeared to be, I will post pics for confirmation. The short version of the story, I bought it. I did a water change in my 29 gallon QT tank. The tank is an established tank that has been running running constant for over 1.5 years. It has a small amount of LR and 30 pounds of LS and an Emperor bio-wheel filter. I placed PVC tubes in the bottom for hiding spots and acclimated the octo for about 2.5 hours. I run all my tanks at 1.025 and the LFS water was 1.020 so I acclimated for a long time. I placed the octo in the tank and after awhile he came out and wedged himself bewteen a PH and the side of the tank. When I went over he would begin pulsing colors. I turned the lights out in the room and went home. I came in this morning and he had wedged himself into a PVC pipe and has been there all day. I had placed a small piece of krill in the tank last night and it appears he ate it during the night. I placed another inside the tube today and I thought he was going to eat it as he balled up around it. However, he then came out to the end of the PVC pipe and THREW IT OUT quite violently. I placed it back in only to see it exit at high speed about 30 seconds later. He really didnt want it! I will setup a 55 or 75 gallon permanant home for him in about a month when he is scheduled to come out of QT. Here are some pics, can anyone confirm it is an Octopus Vulgaris?
