Hi Harry
Congratulations on getting your axolotls.
Did you get them from a pet shop?
They look a decent weight but their gills look very bad.
Do you have any idea how old they are?
What size tank do you have them in and which one is it on the pictures.
You will need to make sure they have some hiding spots if you have the light on as they dont like light because they have no eyelids.
If you haven't already been to
www.axolotl.org then i suggest you have a look through. There is a load of information on there.
But we're here to help if you have any questions.
Also please make sure you use a dechlorinator in your water. And not gravel for a substrate. I think those slate pieces may be a little rough on your axolotls bellies too.
Oh and almost as important....Welcome to the forum..
