My Juvenile Axolotl has got a white film on his gills and his tail is kind of red

[SolarrGalaxy2]

I'm a new axolotl owner and today I turned on the lights of his tank so I could let the plants have some light and stuff for oxygen because before I didn't.

And I looked at him and I noticed he has a sort of white film on the front of his gills and his tail is kind of red. I can also kind of see his veins.
I've also been noticing the past few days he's been coming up a lot for air which is also part of the reason I turned on the light for the plants.

I've been using the dipsticks a lot and everything seems fine aside from the KH which I'm trying to sort out currently. (Hence the oxygen thing in the plants)

I'm not sure what is going on and I really need some help.

This is what he looked like before

This is what he looks like now

I'm going to do a half water change tomorrow and clean our the leaf litter today.

He has also been quite active, I've been trying to keep his water temperature down low under 70°F and right now it's at 68°F

He is eating fine and I'm giving him 2 earthworms everyday and occasionally bloodworms which he eats just fine but I'm just worried because I don't know what this white film is.

I'm suspecting it's because of ammonia and the KH but I'm just asking here to make sure.

He is also being very active and constantly swimming to the sides of each tank for about 20 minutes every few hours.

I'm super worried about him.

Could anyone here give me some advice?

From the pictures I don't see any problems, but that could be because the white film on the gills is hard to capture on a picture.

You say "water values seems fine" but also suspect an ammonia problem?
Do you have the values for ammonia, nitrites, nitrates, pH?

Also, could you take a picture of the axolotl from above? Thanks!

My nitrate and nitrite are both 0, my ph is at around 7.2 and I'm getting an ammonia testing kit at some point today or tomorrow when I can, but I've been looking for signs that could indicate ammonia.

Right now he's swimming across the tank and stuff like really quickly so the pictures will probably be a bit blurry.

Please help I'm really worried
He's constantly hitting his head on the glass and stuff when he goes back and forth and I don't know how to get him to stop, I don't want him to injure himself.

You can see his tail is kind of red from these pictures and I wasn't able to get a good picture of his gills because of how fast.

He stopped when I put the tank lid down, he seems fine now, but his tail is still red and i don't know if that's good or not. I've read on other forums it's because of ammonia but I'm still not sure.

Your Axolotl is very beautiful but I don't see a problem with anything in your axolotl.
PS. I have exactly the same axie!!

but when your axies gills are curled forward it means they are stressed same thing with running into the tank walls maybe try keeping the water temp 16-18 Celsius keep its enviorment as dark as possible, feed daily, and keep an eye on em (pale,acting very diffrent). And if something concerns you I think the best soulution would be to everything would be a trip to the vet.
