New Fish Light On/off?

[J4M3S]

I recently put some rummy nose tetra into my tank and they where doing great, then i cleaned the filter and it has become more powerfull so I have put it on the lowest setting possible but it still seems to scare the fish, I know that the light are suppose to be switched off at night so I did this last night and I woke up to see alot of pale rummy nose tetras, whenever I turn the light off they go crazy so i dont know whether to turn the light off tonigh or leave it on I am going to be an external filter soon to eliminate this problem but what do I do for the next few nights??
thanks for the help

I think you should turn the lights off as normal. Animals benefit from both a day and night cycle. How crazy do they go? Are they hurting themselves? Do they calm down after a couple of minutes or are they going crazy all night? They also should be paler at night, that isn't anything to worry about.

thanks for the reply, that makes me feel better. they go crazy as soon as the light is off then for about 5 mins then they settle down.

you should not just turns the lights right off so it goes pitch black you should put a lamp on so when the light goes off it does not shock them and make them panick then half hour after that turn the lamp off and they should not panick

My fish are the opposite, they go nuts when I turn the lights on. But as long as they calm down your fish should be just fine. Hopefully they'll just get used to it.

Try turning the light off but leaving the room light on for a while. That should better simulate sunset where much of the light goes away, but it is not truly dark for a while. The fish should be able to adapt better with a two step reduction in light than an instant change from brightly lit to dark. Any fish tan is of necessity an artificial environment for our fish. With a bit of thought, we can usually make it seem a bit more natural to the fish though.
