	Fish with issues...
Chel Fingerling Posts: 39 Kudos: 106 Votes: 1 Registered: 17-May-2004	My fish all freak out when I turn the hood light off or on. The tetras scatter and swim erraticly, jumping out of the water and banging themselves into the glass. The guppies do the same, but to a lesser extent. It takes a full minute to get the tank to settle down. Is this normal?

They'll dart around in the dark and hurt themselves by crashing into ornaments. I always make sure the light is on in the room, before I turn off the light above the aquarium, so my fish are not in the dark. The lights in the room provide a dim lighting for the fish.Later I turn off the lights in the room, and the change is not so sudden, so the fish are not startled.

Usually I try to turn on the tank light with some sort of light around the tank so the light itself is not that big of a shock. -------------------------------------------- The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian.
