yes i doesn't matter what size tank you have do at least a 25% water change ever week
a water filter or filter paper
you have to have basking spot like some drift wood or the TURTLE DOCK.Some water for them to swim, you need plants and fishes for security (optional) and you need a heat to go over the basking spot(UVA and UVB) and you need a filter for it to clean the water but you still have to clean every once and a while.
Ammonia is your fishes urine, The small it gives of is terrible and it stresses your fish. It also makes your water dirtier.
* the water denotes the bacteria around the water which is muddy. you filter muddy water by onitting its virus bacteria located on itself. by you. * and also you clean it critically * and also you clean it healthily * and also by removing germs
It never hurts to have a filter it will only improve your fish's chances of survival and decrease your need to clean.
Normally you don't really need to clean the filter unless the flow is too low. If this is the case, you will want to rinse any filter media in a clean bucket of old tank water. Do not rinse filter media in tap water as this will kill off all your good bacteria for your tank.
If you are getting water in the fuel filter, it is coming from your fuel tank. You will need to remove and clean the tank.

You need a purification filter to remove microbes. Boiling the water or adding disinfecting tablets are also helpful but less effective than the filter.
Yes. Just as humans need clean and uncontaminated air to live in and breathe, all fish need clean and uncontaminated water to live in and breathe too. The purpose/use of a filter is required to remove the natural poisons from the water that all fish make simply by living, eating, pooing and breathing in the water. If you could give the fish a constant flow of pure, clean, unadulterated water, then there would be no need for filters.
A fishes habitat is important because that is where they live. They need to have good oxygen, clean water , food , and a hiding place ( fake little tree )
The most common reason for the symptoms you describe is a build up of poisons in the fishes environment (water). Fish need clean, pure, water to live in. Failure to use a cycled filter (to remove Ammonia/nitrite) and also to perform sufficient water changes always results in dead fish.
