In the tropics, days and nights are of approximately equal length so 12 hours on and 12 hours off should be OK. For coldwater fish there can be more variation but i would advise that lights are not left on for more than 15 hours otherwise you are more than likely to have algae problems
Freshwater setup: MUST HAVE: Tank, filter, filter pads/media, heater, light, fish, water, electricity, fish food, place to put tank NICE TO HAVE: Substrate, decorations, tank lid
Use a syphon, a gravel vacuum, or get a crayfish because they just eat fish feces all night long.
When I started my aquarium, the book I read recommended eight hours of artificial light a day. I put mine on a timer and actually only run it for six hours as the algae was terrible. Bear in mind, mine is a ten gallon fresh water tank, a salt water or living tank may be different. NO, fish are used to night & day, just like you! Turn it off when you go to bed or put it on a timer. Allow the fish to have some sleep. Light produce heat as a result of which temperature changes which the fish don't like when sleeping. Also, light disturbs the fish in sleep.
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.
Put it this way, a friend of mine uses her daylight bulb with her lamp, and puts it over the fish tank. I wouldn't use a 100w or 60w really, but all fish are different with their habitats. So i recommend seeking advice from a fish shop near you.
You should be aiming for between 8 and 12 hours. about the same time as the sun is up. this helps with the natural environment of the tank, the plants will grow nicely, there wont be loads of algae everywhere, and your fish will behave more naturally. this can obviously be adjusted to suit when you will be looking at the tank, after all your paying for it :P. I have mine on around 11am-9pm because this is when im most likely to be home! too light can lead to an algae bloom and make your tank go green, if this happens don't leave your tank on for so long. it might also help to keep natural sun light off of the tank. tom :)
depends on the size of the fish, there might not be enough oxigen in a small fish tank.
A black light configuration is completely safe for your fish. It's more recommended for aquascaped fully-planted aquariums, as it prevents algae blooms. If you do decide to use black light, make sure you have plenty of decorations that react to it, otherwise you won't have much use for it. I have a 45 gal. tank set up with a black light for night time, and a fluorescent for the day. It's cool to have less light coming from the tank, and when you stumble out to use the restroom in the middle of the night, and all you see is glowing fake anemones or plastic plants, its pretty awesome. =] Good luck, and happy aquascaping.
Scoop all your fishes to another tank or tub of water and clean the fish tank just as you would normally without the fish
All your fish will die. My buddy dumped a six pack in there and they were all dead in 3 hours...dont put beer in a fish tank
With some it does with others it does not. That all depends upon the retailer you are buying from.yeah mostly it does mine does.:)
That depends on what you mean to say. For example, if you have one angel fish in the tank you could say "That's the fish's tank" meaning that is the tank for the angel fish. If you also had a couple of clown fish, you could refer to the tank as belonging to all three fish by saying "That's the fishes' tank." Slightly different spelling and punctuation
