fish like their bugs...

[Magnum Man]

on the farm, it's fly season right now... the aquarium lights attract them, when the house is dark... this morning, there is a big black fly crawling around on the front of the Hillstream tank... the fish must be able to see it, as several have swam up, and tried to eat it... maybe they are bored, and it's non threatening activity... I hate those flys in the house, but the fish seem to like them

My old betta used to go mad for gnats. I used to have them crawl along the glass and be chased by the fish. Some would even manage to slip into the tank and become a snack.

I’ve had flies walk on the side of my lineatus’ aquarium and they go nuts ! It’s like a cat walking outside a German Shepherds yard .
