It can kill them if you don't have a cleaner fish.
Algae can grow back in as soon as 5 hrs.
Because of algae growth, fish waste, the amount of oxygen decreasing because the fish are breathing it.
yes! unless you have an algae eater, fish don't like it when you have leftover food, fish foods spoil a lot in water Excess fish food will sink to the substrate and decay. This decay will create nitrates that is bad for your water quality and your fish. To reduce the amount of food in the substrate feed your fish less food and replace 10% of the water in your aquarium every week. At the same time vacuum your substrate to remove the excess food and fish waste. To prevent excess food only feed your fish once a day and only enough that they can eat in two minutes. I do this in the morning then give my 15 fish in a 75-gallon aquarium a cube of blood worms at night. See link below there is a video on how to vacuum your aquarium to remove the fish food.
excess nitrogen from runoff would cause excess algae and plant growth, possibly affecting fish populations by decreasing the livable area of the water for fish. the excess algae bloom will deplete oxygen in the water causeing dead zones where there is not enough oxygen for fish to survive.
Some snails have very interestingly designed shells and can add color and uniqueness to an aquarium. Also, snails are an algae consumer and help clean the aquarium. Some fish also require snails as part of their diet, such as some puffers.
Algae is fairly easy to grow if you have fish in your aquarium. If you have a new tank though and your algae levels are very low then you want to get hardy fish to start out with. Remember, it is very likely that most of your starting fish will die unfortunately.
no if you keep the lights on all the time it will create algae faster in the aquarium
Some of them do.Small fish are mostly the ones who eat algea. Most of the bigger fish eat smaller fish.
Plecostomus are fun fish in an aquarium, they eat algae and grow over a foot long.
The "brown stuff" should not be a disease, it's called algae. To get rid of this, move your aquarium away from sunlight and make sure those plants are safe for aquarium use. If you can't move the aquarium away from sunlight, use some medications for your fish tank at your local fish store.
There are many different aquarium animals that will clean algae off the walls of your aquarium. I will name a few: Cories, Plecostomus (AKA, Pleco) and more. There are some algae eaters that are not fish. Mystery snails, freshwater snails, and other water snails eat algae. Ghost shrimp are small and are very easy to take care of. They clean the decorations in your fish tank and eat any uneaten, leftover food.
algae tends to grow faster in clean water. so it depends if the aquarium is clean or the lake.depends on what lake.
