Axolotl not eating

[New to axolotl]

Hi,
I'm a new axi keeper. I've had my 2 for about 6 weeks now and every thing has been going well until the last 2 days. They won't eat. I've tried bloodworms, night crawlers and raw chicken. Water parameters are fine. Plenty of poop and no signs of stress. They're juvies... why won't they eat ?

Sub note.
Although they have a fan, I've been putting iced bottles in their tank to keep temp down because it's so hot atm. Could this be the reason?

I am just as new to taking care of Axis as you are. Just wondering if you have tested their water to see what kind of Ammonia, and Nitrite levels you have in the tank.

How often are you feeding your Axis? Once a day or every 2-3 days?

Do you hand feed them or do you feed them with tweezers?

What is the temperature in the tank?
