In a proper filtered aquarium that is properly stocked and has completed the nitrogen cycle you should be doing 20% water changes once a week. In heavily planted and very lightly stocked tanks you may get away with once a fortnight. If you're keeping very messy fish such as Plecos or Goldfish then you may need to do twice a week!
In an unfiltered bowl you would need to do it several times a week, but no fish should be kept in an unfiltered aquarium unless you are following the Walstad Method, which is pretty complex and technical!
if used in recommended dose it should not affect the fish in the tank. These products are normally made fish safe for use in the aquarium. That said, a tank is normally worse off being too clean rather than too dirty.
Algae can grow back in as soon as 5 hrs.
no...but there is 4 cleaner died during the cleaning process after the day happen..
The only instrument that you need when cleaning a fish is a knife. You can clean a fish anywhere as long as you have water. Some places have restrictions on where you can clean a fish.
The only algae eaters that are safe with goldfish are bristlenose plecos. Weather (dojo) loaches can also be placed with goldfish, but they are not comparable to a pleco for cleaning algae (though they do clean some).
Chinese Algae Eater.NOTE: they can get pretty long. and also the Albino Catfish can sometimes clean other fish.

You rehome the Algae Eaters. Chinese Algae Eaters, what you have, are hardy tropical fish that turn increasingly predatory as they age. They will not stop sucking of slime coat of Goldfish or any other fish who holds still long enough. They are also capable of taking out eyeballs or even eating smaller fish entirely who sit still too long.
no but they are popular for their appetite for algae. if you do get a plecostomus be warned that they grow to about 2 feet long
it can stand without eating forever i guess because it can eat the bacteria and algae in the water
Plecostomus are fun fish in an aquarium, they eat algae and grow over a foot long.
around 2 to 2 and a half years.
If the substance you are refering to is algae and the scenery is moveable you can simply remove the algae covered items and scrub them in clean water. If you are refering to an algae slime on the substrate then you can remove it simply by syphoning it into a container for disposal. If the algae is on plants then having a few algae eating fish species like plecostomus or mollys in there will help keep it under control. Excess algae is usually caused by too much light for too long.
