Hello AimsPink,
Axolotls can shed skin for a number of reasons. If you would like more information, I suggest you take a look at this site:

Fungal infections can be mistakened for skin shedding. Fungal infections look like this:

It is important that you can distinguish between the two symptoms. Fungal infections are often secondary to a primary infection, for example, bacterial/parasitic infections.
I buy 10 feeder fish every week and they are usually ate within 24-48hrs.
I take it that means you did not quarantine the feeder fish before you fed them to your axolotl. Quarantining a newly acquired aquatic animal is very important. The minimum time period for quarantining is 30 days; and is used as a precautionary method to determine whether the new aquatic animal is carrying any diseases that can be transmitted onto your axolotl.
Feeding fish to your axolotl as a staple diet is highly unorthodox because fish contain thiaminase, which can catalyse thiamine; thus, resulting in thiamine deficiencies. You should try and get your axolotl on earthworms and salmon/trout pellets. More information on a nutritional diet can be found in the following the links:

You should really find out the temperature of the tank. Submergible thermometers can be bought for a cheap price at your local pet store. Or if you want to go one step up, you can purchase a digital thermometer. The choice is yours :happy:
Temperature plays an crucial factor in the health of an axolotl. Most people try to keep their tank temperature below 20 degrees celsius. Anything abover 24 degrees celsius is sure way to kill your axolotl, or at least bring about illnesses. Keep in mind that axolotls are "cold-blooded", therefore, they won't be able to regulate their internal temperature the way we (humans) do. So if you place an axolotl in a very warm environment, its internal temperature will be almost directly proportional to the environment, and the opposite is true for colder environments.
But I have been putting ice in the tank...
Don't do this anymore because the ice cube method will result in dramatic temperature flucuations. Try freezing bottles of dechlorinated tap water and then placing them into the tank. Better yet, place your axolotl in the fridge. Information on fridging can be found in the link provided:

He is about 11-13cm long (I do not know if that is classed as little or normal) and the tank holds about 20L of water.
The tank that you have now is far too small. Twenty litres is approximately two buckets, which is very little water. The less water you have in your tank, the greater the chances of facing complications with water quality. Also, a tank with a larger capacity for water has the ability to dilute the amounts of ammonia/nitrite/nitrate. Your axolotl will grow, and can grow up to 30 cm. Therefore, I'd advice you to find larger tank.
Best of luck with your axolotl.
Jay.
