White spots, possible tail fungus?

Hi everybody! I've recently bought my first Axolotl, named Atlas, and I'm worried about him, at the pet store he was in a reaaaally small and cloudy tank, and he already had white little spots on his tail but the guy there told me that they looked like normal skin coloration thingies. (yeah right)
Now he's alone in a 80 cm long x 20 cm wide x 35 cm tall tank with clean dechlorinated tap water and a filter that causes almost no water current, I keep the sustrate and filter clean and change the water weekly (20lts I think is like 5 gallons aprox??), but the spots don't go away and his tail is all wrinkly.
Now, here's the question, should I try giving him salt baths? He's very active and eats well, but I don't want to wake up one day and realize his tail fell off or something terrible like that.
I'd REALLY appreciatte any opinions, I'm about to buy some salts just in case.









As a new member I've already gathered a lot of information from these forums and it's been super helpfull. So thanks in advance!

Actually, those just look like skin pores. I think this is the first time I've heard of a petshop giving correct information.

Look, here's my albino; note the pores. It's perfectly normal for axies to have them, and yours actually seems to be in fine shape, especially if he's eating normally and such (what are you feeding him, by the way?). No need for a salt bath. You'd know if it were fungus because it'd be white, fuzzy, and cottony.

Your axie is fine

His diet consists of chopped earthworms that I pluck from my garden myself, really healthy ones, untouched by chemicals, and amphibian pellets, which he happily gulps down too. Thank you for replying so fast! Your axie looks super pretty!

Excellent Keep up the good work, and thanks =^^=
