Fish would swim erratically, startle for no aparent reason, crash agaist the aquarium walls and one even jumped out and found it dry the next morning.
So no mussels for my fish, after all they are filtering mollusc and with the pollution levels at the seas nowdays they are a potential risk.
These are my own experiences based on my observations on my own fish.
