Well my first question would be how often do you clean your tank? Do you have live plants?
The reason algae forms is because the type of food it needs to thrive is available in massive amounts in an aquarium. Algae feeds off of nitrates, which are a by product of fish waste being broken down in your aquarium. When fish pee or poo it creates ammonia, which is broken down by bacteria into nitrites, which is broken down again into relatively harmless nitrates. The problem with nitrates though is that they are algae fertilizer. Algae use these nitrates to feed themselves.
The best way to combat algae is to use live plants in your tank, because they use nitrates to grow as well, and will start to compete with the algae for the same resources. The other way is to scrape algae off during weekly water changes. I do this every week in my tank, and it couldn't look better.
more fish live in the sea water because how much sea water there is
the marine fish would pretty much suffocate and die. so putting marine fish in fresh water is not a good idea.
If the salt water fish were to be put in fresh water then their high salt content inside their bodies (to prevent too much salt diffusing into their bodies) will have it diffusing out down the concentration gradient; killing them. If the fresh water fish were to be put in salt water then their low salt content inside their bodies (to prevent too much salt diffusing out of their bodies) will have it diffusing in again down the concentration gradient; killing them.
Because marine fish live in salt water because there found in the ocean.
One pound of salt for every one gallon of fresh water. Also, as the water evaporates, add only fresh water...and slowly! When I kept fish, I would drain half of the remaining water, then mix in the fresh water, then put the mixture back into the tank. This prevents the fish from getting a fresh water shock. The water will evaporate and leave the salt behind, so if you add more salt, it will be too much.
i believe you get a motor of what ever type and you would aerate the water,.,.for mostfish,.,.not so much for cat fish
I think you mean tap water. Tap water or pipe water as it is sometimes called sometimes has in too much chlorine. But tropical fish are still fresh water fishes. What I have heard some people do is before they introduce their pet fishes to a aquarium they fill the aquarium and leave the water for 3 days to a week and then add the fishes. This is because I think I was told it reduces the chlorine content in the water making it safer for the fish. But if you are referring to tropical fishes as fish that live in the sea. Well sea water fishes cannot live in water because sea water is not their natural habitat. The fresh water does not have in the essential components for the sea water fish to survive in fresh water. Fresh water fish cannot live in the ocean or sea either this is because the pH of the water will kill fresh water fishes. But they are brackish water fishes which can live in water that has more salinity than fresh water, but not as much as seawater.
If you are talking about fish, I have a betta fish, and usually you use tap water, I do. Also if you would like to have safer water for the fish then you can use cleaners that you can buy at pretty much any pet store. I hope this helped!
Both fresh water and salt water occur in nature, so both are natural. Note, however, that fish that live in fresh water generally cannot survive in salt water and fish that live in salt water generally cannot survive in fresh water.
All fish live in water, this may sound gross but fish drink there own water. water
Your answer that sardine is a sea fish was wrong becaus there are natural sardins growing naturally in fressh water lakes. The fresh water sardins are soled exactly like all other Sardins but the taste and the smell of that kind of sardins is much more milled from the sea water Sardins. Therefore: Fresh water Sardins do exist.
I don't know how much salinity is in fresh water.
