First of all - thank you everybody for all your feedback ...... However - my baby octopus still refuses to eat and if he doesn't eat soon I know he will die ... :-( I have given him every kind of living or dead food he could possibly want without any luck. I tested my water quality levels ... and my nitrates were indeed high (though ammonia and nitrites are perfectly fine). After a large water change my nitrates are now good ... but as of tonight he still won't eat .... Does anybody have any ideas at all?
