Which monster fishies are good at breaking glass?

  • We are currently upgrading MFK. thanks! -neo
In general big spook easy fish in small aquariums do this. They would be more effective if you manage to setup a chain reaction: A fish spooks and run into a rock pile, the rockpile falls and crack something etc

Are you hosting a fish karate demonstration party?

I suggest also design some head/eye/mouth guard for the said fish, breaking glass/running into rocks usually do nasty things to them.
