Iv got a black widow fish ( black terra) and i have had it for about a year but recently when the fish tank light is off and when I put my main light on or my bedside light it starts to flip in circles around the tank
What can I do to stop it

Maybe you should get him a bigger tank. They need to have 10+ gallons so that’s how he could’ve gotten the problem in the first place.
Tetras need to be in groups of 6 and 20 gallons plus .
Could be your shocking your fish by turning the light on .
I would keep the tank light on put the main light on first then turn the tank light out .
that is absoulety adorable but i dont reckon its to good i reckon he is freaking out about the change of surroundings. it was bright and then with no warning its black i dont know but the fish may be trying to get your attention so you can turn the light back on plus tetras need buddies its really cruel to keep him by him self get atleast 5 more buddies for him
Use a dimmer light in ur main light
