Hi everyone. I’m starting a new journal for my pygmy octopus tank. Fluval evo 13.5 Aqueon heater Bumblebee snails Nassarius snails Margarita snails Assorted hermits Turbo snails Assorted mushrooms Zoas Leather corals Macroalgae Octopus joubini I didn’t need to do too many modifications to the tank to prevent escapes. I used filter floss with suction cups attached to block off the overflow. I cut a piece of styrofoam to fit in the large hole on top of the hood. Lastly I stuffed filter floss in the small hole that is in the back wall of the evo. The octopus arrived Wednesday January 29th. I ordered him from salty bottom reef. His first hour in the tank he did a lot of exploring, but after that he has spent most of his daytime hours in one of two crevices in the rock. He seems to move around a bit more at night, although I still haven’t seen him do much moving, I just find him in new locations. As far as I know, he hasn’t eaten yet. There are hermit crabs in the tank and it’s possible he has eaten one, but I don’t think any are missing. I forgot to count how many I was adding to the tank so I’m not positive that they are all there. I am a little worried that he may already be nearing the end of his natural life, hence the lack of appetite and activity. According to salty bottom reef company, this species is seasonally available from October-March. That makes me think that perhaps March is around the time the adults start dying off, and the offspring hatch. I’m guessing the new hatchlings are too small to be caught for the first half of their life, which is why they aren’t available for part of the year. Of course, it’s also possible that he’s simply still acclimating and adjusting to the tank. I don’t really have any good pictures of him yet, since he spends most of the daytime hiding. You can see him in the red light picture I posted, but the rest of the pictures are just of the tank so don’t spend any time trying to spot him. Lastly, to anyone who is considering starting up an octopus (or any cephalopod) tank, I highly suggest joining tonmo.com. The folks on that site have spent so much time answering my questions and helping me out. This is all the information I could think to add for the moment, but I’m sure I will add more later. If anyone has any suggestions or thoughts or questions about octopuses, feel free to post!
