I have had my octo (3rd one ) for about 3 weeks now and he is doing fine except he doesn't come out much. We only see him for a few minutes every day normally. The last two days we havn't seen him at all so I looked at him last night when he's out (4AM) and he looks a little bit lighter in color and one eye looks a bit darker in color. I did wake him and he moved into his cavern quickly annoyed by the light.
This morning he took the seaweed he was on when I saw him last night and dragged it into the opening to his cavern to cover it. I am guessing this is because he was annoyed by the light, but am not sure. Is this normal?
He is not as curious as my last two octos and keeps to himself. Other than his lighter color and darker eye he looked and moved as normal. I am still concerned because I simply can't view him as readily as my past octos. Any thoughts?
All I can think of that's different is changing to a different salt. I change 5 gallons at a time in a 50 gallon tank twice a week. I have only used this salt on the last 10 gallons. Should I go back to my old salt or am I being paranoid???
Thanks for your advice!
