I change everything every time I clean the tank and Itza doesn’t seem to mind, I feel like she is very curious to see what’s new, she was very friendly today that I cleaned the tank so I am starting to learn to play with her and not freak out, maybe it’s because she has never been in a natural environment, but I can leave the tank empty but for her favorite hiding place and she doesn’t seem to mind, is like she loves exploring the bare tank and new places ...and for example she really freaks out when strangers get close to the tank (moves suddenly inside and gets full black) but me cleaning is not an issue for her, I have a new more natural lay out this month, with an oyster I bought in the supermarket one month ago and was in the sump, It’s less colorful but I will see how she likes it, also she is not growing as fast as she should so maybe as a pet she will be smaller as her farm living siblings which is great because maybe she can live longer and in a smaller tank, since I am trying to launch octopus maya as a pet this can be great... time will tell...
