Ok so this is not only my first octopus but my first journal. I recently purchased an octopus at a local fish store under the assumption that it was a dwarf species but it turned out to be a briareus. From what I've seen from the video about Kalypso I'd say my octo was about 17 weeks when I bought it. After about 3 - 4 hours of acclimating I placed the octo in my tank and it quickly crawled to the back of the tank. Eventually she crawled into one of the live rocks and I hadn't seen her for a whole day. The next day I found her crawling in between the rocks. She started eating all my crustaceans instantly. I had to rescue my horse shoe crab and place it in my tank at work. Over the next couple of weeks she's settled into a specific rock. This makes it really easy to find her being as the rock only has one main hole that she can fit into and she is easily seen from the outside through the holes in the rock. It only took a few days before she would eat from a feeding rod and she took the shrimp instantly without hesitation. About a week later I was able to start hand feeding. Again she instantly and willingly took the shrimp. The majority of the time she spends in her den and only comes out a few times. Usually around 6:00 - 7:00 am and sometimes around the middle of the day. My fiance told me she's seen her out and about around 3:00 pm. I've had her for about a month now and she's almost doubled. She doesn't eat much that I can tell. I feed her about have of a thawed shrimp tail every two days. Whether she's eating hermits in my tank or not I can't tell. There are still alot running around in there. I try not to feed her too much so as to not excel her life span and also because when I feed her she eats and then spends the next day in her den, only coming out to eat. I find this to be curious because the octopus we have at my work (O. Dofleini) comes out all the time to crawl around and swim, and is well fed daily. I know I keep refering to my octopus as a female. This is because I have yet to find the presence of a hectoctylus (spelling?) I just recently found a post of someone who just recently purchased what looks like a male briareus that looks of the same age. I'm cursious to know if this octo is near by. I would love to find a male to breed with mine. Anyways I know I'm ranting. I just wanted to try my best to sum up the past month that I've had her and not posted anything. I'll try to keep this thread more up to date. What is the best tempurature to keep O. Briareus?
