Yes.
It is alright if your axolotl swims around at the top of their enclosure. This may however signify that they need more oxygen and that you should clean the tank more often.
I have never kept them but at least a 30ltr tank is advised by experienced growers for one Axolotl and an extra 10 ltrs needs to be added for each extra Axolotl.an axolotl tank should be at least 10 gallons.
They like a bit of old pipe so you can make a little tunnel for them to hide in.
I would say that it would depend on the specie. You should spot clean feaces as soon as you see it so a full clean out could probably be done once a week maybe a bit longer
you have to use your hands....
If axolotls breathes oxygen, then yes.
Get a net, or fill up the container/bowl where you're putting your fish while you clean the tank, and try to use your hands to pick them up. I've done that a few times. Or try scooping them up into the container/bowl when you're getting the water..
Pick up a good fuel injector cleaner from Autozone or somewhere, and run it through the gas tank with your next tank of gas.
No. They only eat algae. They are no fish that are tank cleaners.
Although there are a lot of products in the stores that say you can clean your own septic tank, it would be better to hire someone. It can be a dirty job and if you make a mistake, you will have an even bigger mess on your hands.
Floors mr. clean septic tank
There are a couple of reasons why your axolotl might not be eating like temperature of the tank water and if the water is being cycled, and if you are feeding your axolotl only one typeof food maybe try something different,
