no if you keep the lights on all the time it will create algae faster in the aquarium
Yes, prolonged exposure to UV light can harm and potentially kill fish by damaging their skin and eyes, disrupting their immune system, and affecting their overall health. UV light can also lead to the growth of harmful algae in fish tanks or ponds, which can further harm the fish.
no there would be no harm as i always have fish and a glass of milk at dinner time :) but there is a strong chance of heart burn but no serious damage :)
No, as long as the light is not too bright. If you get castle or something to put into the tank, then it can stay in there without being directly in the light
fish harm rivers and we do by dumping our rubbish in them
it will be helpful for some fish to be luminous because if they life at the bottom of the ocean, no sun reachs there so then they will have to have their own light. they also might need to luminous because if another fish comes by to fight or harm the fish and its "family" it will use its light to scare the fish away and the light works the other way sometime it might being smaller fish of stuff closer to it so it will have eat it or something like that.

leave it there. It won't harm your fish.
Fish always have gills
No, they won't.
when people harm the environment when they fish.
Sure you just need a hook for small fish, but it is always better to match the fishing tackle to the fish you angling for. Ideally for small fish you should be using a light or ultralight fishing rod and tackle. With a carp rod you many not always be able to detect the bite of a small sih. Also the action will be to heavy for most small fish.
