Injured tail ?

[Julieroo]

We recently moved our axolotl t

o a bigger tank but I'm not sure if it's tail had got caught in something and if its something I should be concerned about.
Pictures of tail and tank set up
Thank you

the extra skin isn't from damage, it looks more like regression which can be caused by water parameters being off. how are his/her gills?

I dont see much difference in the gills to be honest - they've never been as full looking as some of the pictures that I've seen on here but they don't really look any different from how they usual are.
The axie is approx 3 years old .
I'm not quite sure what/ how to check stuff to do with the water, my granddaughter bright it with her about 6 months ago when she moved in and it has just gone into her dad's old fish tank about 3 or 4 days ago.
Any advice would be very much appreciated

Just a thought - we used a different type of sand, my son got it and said that the pet shop only had the black one - and I'm sorry if I sound really dense but could you please explain ' regression' to me, very new to this and trying so hard to get things right !

 

[wolfen]

regression is when an axolotl reduces the dorsal fin and gills, this is either done to protect itself from toxins in the water or to morph into an adult salamander.
if this was a recent event I would expect to see some reduction in the gills which they aren't, as it is though the tail should grow back to normal length and the dead skin at the end will fall off/disappear in time, just make sure to do regular water tests.
also because I can't see one in the tank, adding an air-stone will help keep both your axolotl and filter healthy.

Thank you very much I'm so glad this forum exists, it's so hard to find any advice/ information anywhere. Getting straight into the water tests and will be more vigilant.
Than you so much !
