To be fair jellyfish are about the least 'animal', animal you can have, it's a little like imprisoning a house plant.

To expound upon this, we have no reason to believe the jellyfish even knows what's going on, let alone cares. They don't even have a central nervous system- WORMS and FLEAS are more likely to have an opinion on the matter than a jellyfish.
