My octo must be an exception to the posts that I see on this board.
In the last 8 days, he has only eaten TWO hermits. The last time I saw him was for about 5 seconds, over 24 hours ago. I would say that I've seen him for a total of about 2 minutes since I put him in the tank, and 1 minute of that was when he first started exploring the tank.
This guy NEVER comes out, never likes any light, and has not taken ANY food from me. The only time I can get him to eat is if I can find him on the glass, and drop in a hermit near him. He then lets it sit there for 20 seconds, then grabs it and goes and hides.
I'm getting frustrated because everyone claims they can feed their octo, their octo has moods, likes to play with the feeding stick, squirts them with water, and even gets to know them.
My octo is 180 degrees opposite. So far, he doesn't take food, has only one mood (afraid of everything), doesn't play, doesn't squirt water, and hides 24/7.
My best chance of even seeing him is after the tank has been dark all night. Even the slighest light in the room (I have a light on a dimmer) is too much.
I'd like to at least watch his behavior, be able to feed him, or check to make sure he isn't dead. I've resorted to just dropping in ghost shrimp in the hopes that he can catch them and eat them. He hasn't eaten anything else in my tank (peppermint shrimp, snails, etc.).
Oh well - I guess only time will tell.
