Armstrong said:I don't think anything would happen. I wouldn't say Squids are an octopuses main diet, but most likely...if the squid got in contact of the octopus, and the octopus was quick enough to catch it, the octopus would most likely eat the squid with no problem. If the octopus is very, very tiny, then I wouldn't even say anything would happen.
Iv always wondered what would happen if a Cuttlefish and a Squid were together. I read they aren't allowed to be in the same tanks together. What happens if they are?
