when do marbled catsharks become more active

[Comatose]

No. Let your shark adjust to it's surroundings. Not eating in the first week is normal, and you might just be stressing him.

This is the shark with the injury, right? Take care of that first. I've never seen a coral cat sit in the open like that and it could be a sign of distress. Once he's cured, try some whole smelt (not fileted or cleaned), cut them into bite size sections and feed him ones with guts hanging out. I've never seen a healthy shark turn that down.

Squid, he shouldn't refuse it. I run actinics all day long so the sharks never have full lighting and that seemed to bring them to life during the day. Every time I approach the tank they swim everywhere. I don't target feed either, the sharks have to find their own food and are very good at it. I think it has made them more prone to swimming and better navigators of their home.

so what should i do ? put a piece of squid on the sand bed

I just drop it in from the top... sometimes it goes on the rocks, sometimes on the sand.
