my octopus died this morning, last night he was swimming around wierd like twitching, and since i got him tuesday hes legs have been curling alot and hes always been like trying to turn himself inside out and he died this morning
ya the tank has been cycled since july 24th 2007 and the specs of the tank are fine exept for nitrate went from 0 last night to 20 right now. he has been dead for a while, he mustve died last night while i went to bed and he was stiff this morning. theres no copper in the tank at all and im going to do a 10 gallon water change.
It is possible that your octopus died from the stress of capture, shipping or collection and that it had nothing to do with your system. It is also possible that the octopus was already near the end of its life and the stress of being shipped and introduced into a new system hastened the end of its life. Sorry
i recently had a puffer fish come to me that was all but dead on arrival. after i took great care setting it up and acclimating it but it just sat at the bottom of the tank gasping, apparently unable to move and died later that night. Even if you didnt do anything wrong, i know it's really hard to watch an animal die under your care and feel like you must be doing something wrong.
just be really scrupulous about checking every parameter and make sure everything has been and remains where it should be before giving it another go, and try not to let it get you down.
being transported is a rough gig and more often than we'd like it kills our animals. Do you keep a logbook of parameters? that can help reassure you that everything is stable and regulated
