When a freshwater aquarium is not overstocked, the normal water movement provided by the filtration system will be enough. It is not necessary to bubble air through the water to 'aerate' it. This has very little effect on the oxygen content of the water because the bubbles are in contact with the water for only seconds before they reach the surface and burst; gas exchange occurs on the surface of the water itself. Aeration without a filtration system is pointless - as is trying to keep fish at all without a filtration system. The job of the filter is to process ammonia, which is constantly produced by fish and is highly toxic. Bacteria live in the filter media and remove the ammonia from your tank. This is called the nitrogen cycle and very few pet stores will tell you about it. For more information on how to 'cycle' your tank, try some fish forums. The members are always willing to help.
Depend on the fish you have
their is no aerator
A fish AERATOR is a device used to add oxygen into a fish tank so that the fish do not suffocate as they consume the increasingly depleted oxygen supply
Remove the sick fish..... the fish that has the ich should be put in a hospital tank then treated for ich, corals do not get ich, only the fish, so a ten gallon tank with a aerator would be ideal for a hospital tank....
The aerator in a fish tank pushes air into the water. Some of the oxygen from the air stays in the water so that the fish in the aquarium can breath it. Even though fish live in the water, they still need oxygen to live. When they pass the water through their gills, the oxygen in the water is taken into the fish's blood stream.
The purpose of an aerator in a fish tank is to increase the surface are of the water next to the oxygen source to allow a more efficient transport of oxygen from the air to the water for the fish to be able to breath. A few large bubbles have less overall surface area than many small bubbles.
It is necessary to schedule a septic tank aerator replacement when the aerator is not functioning properly, causing issues with the septic system's performance. Regular maintenance and inspection can help determine when a replacement is needed.
If a fish is acting lethargic than you should do a large 50-75% water change pronto. Also, try using an aerator in the tank to try to raise the dissolved oxygen levels.
The machine used in fish tanks that makes bubbles is called an air pump or air stone. It add oxygen to the water and keeps the oils from coating the tank.
Your fish is gasping for air because it needs air to live. if you don't already have one, I recommend getting a aerator. This allows air to be in the tank with them still being under water. The fish fuzz, I don't know about.

If you don't have an aerator, you need to change the water very other day at least--but take care not to stress the fish in doing this. The easiest solution is to get a proper aerator.
