They can pick up the change in water pressure and flow when they get close to the glass, or maybe the change in light. Otherwise they'd constantly crash face first into the glass.Got me interested now. Would a fish realise that there is glass there that separate them or do they not have any perception of glass. Would a fish become agitated if it saw a predator in another tank.
Lol kinda funny if you think about it lol like what you looking at huh lol
