I've been keeping track of this with bimacs for a couple of years now. There's no one overriding cause. Some early deaths last year were vaguely due to human error (escape where the tank wasn't properly sealed, family member turning up the temperature on the heater, power stayed off during a weeks absence, etc.)
But this year we couldn't determine why some of them died. Reason unknown. There were several that survived a few months and then passed away.
I will continue to track this and hope that we gain some additional knowledge.
yeah, thank you. I figured someone more experienced than I on here would have been keeping trakcof this and they were. I am almost completely ready to go on my octo tank which with research and all is almost a year and a half in the making. So I am real edgy right now about actually getting the octo. I want to make his first two or so months as good as possible and am trying to gain common mistake info. thank you for the help and any other knowledge that would help me in this reguard that isn't regular octo care would be greatly aprecciated. thanks again,
My last octo (a pygmy digueti) only died when subjected to having crawled (still never did find out how...clever little bugger) out of his tank, across a 40 foot expanse of carpet, underneath the front door (tight squeeze, too) and almost all the way out the driveway to the street...he was quite old for a pygmy (almost a year) and full of beans...you have to admire his spunk, but it sure was depressing...
ooops, sorry for forgetting that not everyone is as insane as me and uses these terms!
Mixing = Acclimatising
when you float your bag in your tank to correct the temperature between the two and then slowly mix the water of the two of them together before putting them in the tank.
Ideally with Octos i tend to spend well over 30 mins mixing them, after they have been floated for quite a while. I tend to give 10 minutes for every degree of difference in the water temperatures (for examply, I get a bimac in, my tank is 21 and the bag water is 24 24-21 = 3. 3x10 mins = 30 mins floating before I start mixing the water). I've done this with hundreds of cephs and have only ever lost ones that look like they are dying in the bag and have been badly packed (usually Eldone cirrhosaare the worst)
