Interesting Observation Hmmmmm.....
I have a 20watt 12v underwater spotlight that shines up toward the waterfall
from the opposite side of the pond. The beam of light shines upward at about a 20deg angle. I have noticed at night that when the goldfish swim perpendicular to the beam they "tilt" and orient themselves 100% broadside to the light no matter which direction the are swimming to. This makes them appear to be leaning sideways as they glide through the water. When I first saw this last season at first I thought they were sick but now it is normal. Any comments? See my pond www.htcomp.net/rhino_4_good/index.htm "Without the second ammendment, the others are just suggestions." |

This is common for allot of fish. I find it evident in my aquariums in the
evening when the tank light goes out for the night and I sit near my tank with my reading lamp on the fish seam to roll over on their sides and swim along the front glass. --- Outgoing mail is certified Virus Free.

People think I'm crazy, they have no argument with the "tilting" thing, they just think I'm crazy. --- Outgoing mail is certified Virus Free.

The has been discussed in rec.aquaria.freshwater.misc a few times. Apparently fish orient themselves to the sun, or surface of the water. If you place a light from a different angle, they will orient to it as if it is the sun. The thread in r.a.f.m that I remember had to do with someone wanting to put lights in the bottom of their aquarium. BV. |
