That would be my understanding too, but I never cease to be amazed these days. I would remain inclined to think that ingestion of algal material was accidental, but I would not go as far as to say they'd never do it deliberately (my cats eat grass, I believe, when they've got gastric 'issues;' having said this, my cats have issues!).

ALL cats have issues, that's what makes them cats.

Yes, because it makes them barf! We had a 'bulimic' dog that used to do this too - learned to keep her outside after she'd been grazing. :/

Perhaps you should walk your octopus or squid every day, so it can chew its cud, barf, and not soil the tank

That would reduce water changes but what would the neighbors think?

CephBase had 1000's of predation records. Among them was a single record of algae in a ceph's stomach. The papers authors and I both believe that this was an anomaly. As far as I know, all cephs are predators with most preferring live prey.

I'd agree, we've had times when we've had to let the octopus go hungry for a few days (ran out of crabs and bad weather so couldn't get the boats out) NOT a good scenario, anyway our octopus wouldn't touch fish fillets never mind the seaweed in the tank!

I don't like to wander off topic frequently, but since the door has already been opened...
My late Lab / Mutt loved veggies. She would steal carrots right out of a neighbors garden (to his amusement, not anger) and oddly, loved Romaine lettuce, but wouldn't touch Iceberg. Skinned apples, oranges and grapes (only if I peeled them) were liked as well - note that these skins are supposedly not good for canines - the pectin ya know...

I have often wondered why some aquarists will feed their wet-pets terrestrial foods like spinach for herbivorous fishes and garlic, of all things.

You might as well be asking why people top off at gas stations

And canids are often quite omniverous, wolves etc in the wild will eat berries etc, my dogs also love carrots, apples, bananas and also grapes (although they never get those as according to our vet the whole grape is toxic!). Seamus my spaniel LOVES raspberries off the cane, it's so funny to watch him curl up his lips so he doesn't get prickled and nip off the berries! BUT I've never seen this behaviour (plant eating) in cephs, I think their protein based metabolism just can't deal with the cellulose, and they just don't seem to recognise algae a potential food source (unlike my garbage guts dog!)
