Abnormal blackening of toes

I know Axolotles toes blacken as they reach sexual maturity but it was mature when I bought it, a few weeks ago. The dark tips of the toes seem to have spread now accross the back of it's feet slightly over the last day or so and this seems strange. It doesn't seem to be in any discomfort. Am working on getting a picture up,

Yes, a picture will do a great deal in helping everyone assess the situation.

I'm finding it hard to get a picture that actually shows good detail of the problem, I've never seen anything like it. If I don't manage to get a picture, is there any advice you could give me?

What colour is your axolotl?

without a photo it´s difficult to give an advice, because I for myself don´t really know what you mean. I never heard of that before.
What is your axies behaviour? Does he react normally or is he showing any signs of stress or illness/indisposition?

It's spread onto the backs of her feet, it's a white axolotl, behaving normally, but obviously it's worrying because it's something I haven't come across before. I already think it's possibly compacted, but no idea. Clearly it's not a usual symptom of anything obvious. Almost looks like it could be dirt?

Sometimes my axolotl feet seem 'dirtier' on some days. What do you have as a substrate?

What substrate is it on? Mel

my axie seems to have some similar problem, first one of his hind leg toes appeared like with blood and then part of it was lost, then another toe was looking red too and now a third, and i think he now has another one in the other leg

strange thing is he lives in a bare bottom tank, i have some large river rocks and a fake and a real plant with a pot for him to hide, so i have no idea how he is hurting himself like that

i am cycling a bigger tank now but i am worried since i dont want to use substrate, just rocks and a log and a pot for him to hide, and plants... but i have no idea how is he doing that

i'll try to post a picture, i think i did post one in another thread but it's quite difficult to take on of his toes!!

he's a golden albino at about 15 cm now, maybe his tank is too small now and he's crashing more? the tank is 50x20 cm
