after the death of my previous octopus (he died on the way to my house from the store by inking the water in the bag) my sister surprised me with another one. she is doing fine it looks like but a little shy. i have 2 overhang bio-filters in a 55 gallon tank with a heater. they told me in the store that i wouldn't need the air pump because the overhang is exposed to enough oxygen and the octopus should be fine. the water levels are all perfect according to the store i shop at as they do free water testing and my water temp is at 80 degrees. shes kinda medium sized. plz help me identify her!
