With an old octopus, should low salinity and or water quality be a concern for behavioral changes, or should it just be chalked up to old age?
Nancy;155550 said:From what I've read, the octopuses that live near the shore and sometimes in tidepools (like O. bimaculoides, the bimac) are more tolerant of changing conditions than the species that live in deeper water. This is one reason why the bimac does well in home aquariums. Heavy rains and outpouring from rivers can result in temporary lowering of the salinity in affected areas.

environmental issues
I think basic things like temp, salinity, O2, CO2, NO3, PO4, ph...etc. Probably prudent to add things like you mentioned - cover, predation or tyrants, flow...environment you are housing it in
