Please help my axolotl has not moved in 2 days

[Darfin]

My usually very active axolotl has been barely moving (other than flapping his gills every once in a while) and when I tryed moving him from where he was he just slowely walked back to another spot. Afew days ago he got caught in side a plastic decoration and a little scratched up but I'm scared that this is worse than that. I replaced the plastic decor with natural limestone and driftweood, could he just be shocked by the change in decoration?

Keep an eye on him. Mine will stay in a hide for days.

Yeah, sometimes they are not active for awhile. Have you tried feeding him a good earthworm?
