hahaha
nah, seriously...
I used to be very scared of "catching" my axie too, and she's a timid one too...
You can try with the container, removing the hideout, or with a net and transfer him to another container, with dechlorinated water, at the same temp of his tank
then you can examine him well (with a magnifier even!) and remove anything that may be stuck there
It's scary but don't worry, he'll be fine, just be very careful while "catching him", what I did the first time was getting him into a right about his size tupperware into the tank, closing it and removing it closed, when he was bigger I caught her with a net and transferred her to a bigger tupperware (being very careful with the net and using my hand to cover it while I took her out)
