Either water splashed into the bulb, a wire is lose or has frayed or you have an arc forming from the bulb seat to something. In any case do not continue to use the fixture until it is resolved as it may present a fire hazard.
The energy for the plants in a fish tank is supplied by Light.
It is instinct for fish to hide from danger. It is normal for some fish to hide from the light.
Turn the light off or get a smarter fish.
that depends what you want to do with the tank if you want a planted tank then dont go with a LED light inless the plants are very hardy and dont require a lot of light. if its just for fish go with the LED light. i have a LED light on my fish tank and my fish are doing great. i dont have any plants but i might get some hardy, low light ones. LED also saves energy
Well, no but they are a lot better with them. For your fish, not for show, if you have gold fish, if you don't put a light in they will go silver. This is because of the lack of light.
if you have a tropical fish or a filtered tank than yes you do need a light
yeah. it can
well it has to have light if you cover only the top it will be ok:o
yes, it is actually better, as some fish can be frightened. Never turn on the light after newly buying and releasing fish into your tank.
a light might be nice but its not expected for the fish to stay alive.

All tropical fish need light, as they tend to live near the surface around coral reefs. It is no different if the fish is kept in a tropical fish tank. Too much light duration will result in excessive algae growth in a fish tank. Therefore, light duration should be regulated to keep algae growth to a minimum.
