feeding axolotls certainty is different than feeding fish, however once you get accustom to it, it can be quite simple. First off, the age and size of your axolotl determines how often you should be feeding them.
A baby axolotl ( 1- 3.5 inches ) should be fed twice a day. A Juvenile ( 4 - 6.5 inches ) should be fed every day or every other day, and an adult ( full grown, each adult varies in size ) can be fed every other day or every 3 days. Remember that an axolotls body should be about as thick as their head when feeding.
There are quite a few different kinds of foods to feed axolotls, and different methods of feeding them. Here are the most common food types and easiest ways to deliver the food.
Frozen Blood Worms
If you plan on using a feeding bowl for your tank, you simply thaw out blood worms using some tank water in a separate container, once the worms are thawed out suck them up using a turkey baster, and place them into the feeding dish at the bottom of your tank. Collect left overs after your axolotl is finished eating so that the food doesn't fowl the water.
Live Earth Worms
When feeding earth worms you need to make sure that the size of the worm isn't to big for your axolotl, if necessary you can cut the worm in half or even into quarters using a pair of scissors. You can then drop the worm directly in front of your axolotl, or you can use a pair of tongs to hold the worm in front of your axolotls face until it eats.
Live Feeder Fish
If you choose to use feeder fish as a part of your axolotls diet you will need to take into consideration the hunting skill of your axie. If your axolotl is active and fast, he may be able to catch live feeder fish that you place in the tank. If your axolotl is more docile however and cant catch the fish you may use a pair of tongs to place the fish in front of the axolotl like with a worm.
Sinking pellets
Some people choose to feed their axolotls sinking pellets, if you take that food route you would simply place the pellets into the feeding dish.
Regarding how well axolotls can jump, you would be surprised. Axolotls have a lot of power when they want it and I have personally watched mine jump to the lid of my tank ( 5 inches above water level ) an axolotl could easily jump out of your tank if it does not have a lid. I would highly recommend finding some kind of cover for your tank before you place your axolotl in his new home. You can use a screen of some sort, or look around your house for some object that is approximately the same size as your tank to cover the top without blocking air flow. Better safe than sorry!
Your tank temperature should be just fine and if you become concerned about water flow you can always add something to block the outflow. In my tank I use bath loofahs on the outflow, they are extremely effective and I have no water movement. my axolotls also enjoy climbing onto them. Its a cheap and quick solution that works quite effectively. :wink:
Lastly, I have no experience with ich. I have kept tropical fish tanks for the last 10 years without experiencing ich, I have had betta fish, and now axolotls and have never run into the problem. That is something you might want to research on your own or wait for a more experienced owner to tell you more about.
