The white scale on the inside of the fish tank is from a buildup of minerals that were in the water.
Inside the tank as it is for you to see the water temperature.
take the fish out immedietly and drain the water. after you have drain the water wipe the inside of the tank with water. DO NOT USE SOAP TO CLEAN THE TANK, ONLY WATER. after you have done all of this clean out your filter and put a new filter sheet inside of the filter.
No, but it is necessary to replace 20-30% of the water of a fish tank per week. This can be achieved by installing a filter inside the tank which will automatically recycle and clean the water.
yes it is a mechanical mixture.
Not in its self. The fish could jump out of the tank and land outside the tank, though.
What will happen if water gets inside gas tank
Salt Water Fish
There are 4 types of fish filters: Inside tank attached to a corner, outside tank attached to corner, outside tank canister, and under the gravel. All work by drawing water from the tank into a container which holds a filter that collects and purges waste, dirt, and similar products before returning the cleaned water to the tank.
It is best left untouched for a couple of weeks, during this time water (same temperature as the water inside the tank) can be added to the tank in order to dilute the waste substances. The movement of water inside the tank should be very low as it can break the bubble nest. after eggs are laid, the male betta (parent) should be the only fish in the tank and after two to three days, he should also be removed from the tank in order for the fry to develop. Otherwise the fry (baby fish) get eaten.
Assuming the dirty fish tank has had fish and water in it, without doing various specialised water tests it is impossible to tell what is in it.
It might be unsafe to drink because fish food, fish scales, fish waste, and many different kinds of bacteria are in fish tank water.
