Canary blenny not eating

[leventis72]

Purchased 2 weeks ago and hasn't taken any food yet. Have tried Pe Mysis pellets, frozen brine shrimp, frozen Mysis shrimp and today frozen fish eggs as a suggestion for finicky eaters with no luck. He is active all day always looking and sand bed so he has am appetite for sure. Stomach is skinny of course. I have no pods and tank has been running for 2 years now. No other fish bother him. Since they are omnivores and planktivores wondering if nori wrapped around a piece of lr rubble be the answer? No algae in tank to graze on..
Any help appreciated as 2 weeks is about the length they can go without eating before starving themselves.
Thanks in advance

Have you tried algae sheets?

How about target feeding?

What are the tankmates?
