We got an octopus today from Aquacon, but not sure if it's a BRIARIUS or not!?!? He's much bigger than we were expecting but that's okay. We have 2 different tanks that have been running for months and empty. I drip acclimated him for about 2 hours and when he first when in the tank, he went straight into a cave. He's now out and has been exploring for about a half hour. He seems to be staying near the top though! Hope that's okay!
