Hello all. Thinking about a fish only tank with a 6" octopus vulgaris (6" is the tentacle to tentacle length when fully stretched out). was wondering if this would be safe to keep with a 4-5" puffer, trigger, and other commonly kept aggressives (4"+)? Any experience with an octo in a fish only tank sharing with other fish? (please dont respond with an octopus lecture, have kept them in the past, just never with fish)
