Basically this type of fish kill is caused by nature not being able to contend with mans input. Usually caused by soil or fertiliser run off from farms, excess nutrients get into the water ways/lakes etc. Then nature tries to use up these excess nutrients in the only way it can and that is by the growth of Algae. Algae are tiny plants that will use up the chemicals N.P.& K. and the many other trace elements that have become suddenly available in the water. When this happens it is called an "algae bloom". Then, when all the excess nutrients have been used up by the algae, there is nothing for the it to use up (eat?) so it dies. Now we have a different problem. The dead algae decays. This decaying process is speeded up by aerobic (oxygen using) bacteria which create a lack of oxygen in the water. At this stage both the bacteria and the fish become short of oxygen so they die off (suffocate) too. This creates another load of decaying matter and another excess of nutrients N.P.K. etc etc etc. This has started a continuing circle of algae bloom and decay which continues on taking nature a considerable time to clean up, settle down and get back to normal.

∙ 12y agoThat depends under what circumstance you are asking the question. If you have completely overrun with algae, then the answer is likely no, because your nitrates have climbed too high feeding the algae all the nutrition they need.
However, you will often see fish picking at algae on a tank. And in most cases this is completely natural. There are even fish that do nothing but eat algae and wood for a living...yes...wood. Most folks called them plecos or algae eaters.
For example however, my fish can often be seem picking off tufts of algae from the sides of my tank and my driftwood. And yes, in many cases it's good for them. Plants contain different types of nutrients than flake or pellet foods do.

∙ 12y agoNot really, unless you have a lot of it and it makes your tank cloudy .If it is bothering you, you can buy some bristlenose catfish or on last resort, there are chemicals available for algae removal.
Wiki User
∙ 13y agoyes because if a fish is in algae too long the algae can get in its gills and block its air ways
Wiki User
∙ 13y agono it may make them sick but it is not deadly. ways you could fix it is get a snail to eat the algae
Wiki User
∙ 12y agoNo but they do get territorial as they age so they might attack other fish. As far as I know they definately won't kill any fish
Wiki User
∙ 12y agoIt depends what type of algae killer it is. The directions should say on the label.

How can algal blooms be harmful to aquatic life?
because euglenophytes absorb waste and such... they recycle it and so!.. when theres to much waste the euglenophytes make things called "algal blooms" the algal blooms deplete the waters nutruents and oxygen killing algae and other organisms
How can algal blooms be bad?
Algae blooms are a form of bacteria and can cause skin irritation or respiratory irritation in people who get in the water or handle the algae. Some blooms of blue-green algae can produce chemicals that are toxic to animals and people who drink the untreated water.
What is the main cause of fish kills in rivers polluted by fertilizers?
High nitrate levels in the water cause an increase in algal growth with reduces the amount of oxygen in the water, which in turn cause the fish to die.
Why is eutrophication bad?
Natural eutrophication isn't as much of a problem as artificial eutrophication. Artificial eutrophication is caused by humans (fertilizer from farms, lawns, gardens, etc. pesticides, herbicides, road chemicals, etc) these chemicals cause eutrophication to happen much faster than it should. If eutrophication happens faster, algal blooms (large floating mats of algae) form. When algal blooms decay, the bacteria that decays it depletes the oxygen in the lake or pond and the fish die of suffocation.
What causes alge blooms in ponds?
Algal blooms result from an abundance of nutrients, particularly phosphorus. Too much carbon and nitrogen have also been suspected to cause algal blooms, but little research has been done to prove it. When Phosphorus enters into a water system it causes an increased growth of algal. It usually takes over causing many plants to die. The dead matter becomes food for bacteria that decomposes it. Because of more food for the bacteria, the bacteria multiply and use up the dissolved oxygen in the water. This results in many fish and aquatic insects dying because they cannot survive. This results in a dead area.
What consequences can result from algae and bacteria growing too quickly?
When algae and bacteria grow too quickly, they can cause harmful algal blooms (HABs) or bacterial blooms. These blooms can deplete oxygen levels in water bodies, leading to fish kills and other marine life die-offs. Additionally, some types of algae and bacteria produce toxins that are harmful to human and animal health when ingested or during contact.
How does the use of fertiliser damage the environment?
In Australia the use of nitrogenous fertilizers in the Murray-Darling basin has been a cause of some dramatic algal blooms in the slow flowing Darling river. These massive over populations of algae feed on the "second hand" fertilizer and rob the water of oxygen. All water dwelling creatures in the bloom "zones" are affected to the extent that entire fish populations die.
What are the results of some harmful algae blooms?
harmful algae blooms(HAB) cause the following condition 1- Red tide phenomena(change the usually colour of the sea into green,brown and red )due to pigments that oroduced by this algae 2-this HAB secret toxin this toxin cause damage to central nervous system of fish and caus paralysis to it then die
How does fertilizer kill fish and other aquatic life?
Fertilizer IS nutrient rich. When it gets into lakes and ponds, it causes massive algae blooms. These massive algae blooms soon die off, contributing to massive amounts of carbon dioxide accumulating in the lake or pond (and thus a decrease in oxygen concentration). Such a decline in oxygen concentration will suffocate fish and thus cause fish kills.
What problems are associated with algae blooms?
Algae blooms result from over fertilization of waters and often result from over fertilized fields and sewage or manure losses.The blooms themselves:are unsightlyremove dissolved oxygen from the water when they die and decompose (kill fish)are odorous and cause taste problems in drinking watercover the lake bottom reducing breeding areas for fishchange the ecology of the benthic organisms
How did a fish die?
water temperature can “shock” the fish and even cause them to die! The water PH and hardness are also critical; the sudden drastic change in either of them can cause fish to die. Gold fish Who's Is Die quickly
Which season do algal blooms mostly occur?
Not all flowers bloom in spring. Those that do so largely because they need to set fruit or seed and have it mature before winter. In the winter, the fruits would not be able to withstand the cold and freeze. Sometimes, the flower's petals will wither during and die in the winter, so they must bloom during the spring, the season of warmth and new life.
