You can make your fish swim sideways

Pretty sure a fish swims upright using it's swimbladder mixed with electrical sensations in it's lateral line. Could be wrong though. I've had a similar expirience with a broken heater before though. Made me walk sideways after the 350 w shock of sticking my hand in the tank and being like wow, that's a weird spasm. Do it again wow, it's not me it's the tank. Go get friend. Hey I can't reach that rock can you get it for me? He does the same thing twice lol, proceeds to chase me around the house in anger.

You gave the tank the "look" right?

Fish typically us light to determin which way is up. If you put a light to one of the longer sides of your tank you can make them swim sideways.

I have a good current (water, not electric!) in my 4ft (long) tank, so my Congo tetras swim near the front glass, facing to the left of the tank swimming in the flow. A while after the tank lights go out, but with another light source across the room from the tank, their swimming posture IS canted to the side towards the light. They can be swimming 20-30 degrees off the vertical and I've noticed them doing it since I got them. It's lights out time right now and they are doing it while I type,(I just checked!) so there is some truth in what you say.
Of course, the real fun is when there is NO light in the room and you shine a torch in.....that REALLY screws them up!

Swim bladder is what controls the fish to swim level. I have also see a few fish that has problem with their swim bladders and where sideways and all.... So if the swim bladder is messed up in the fish then u might get them to swim sideways. (happen alot when we fish for fish and keep them in the live wells. for later uses

When they turn around is how you know thats how they do it. When they turn around as a school and they are still leaning toward the same side... well thats just crazy.
