Unable to trap brittle Star

[kris2001]

I'm unable to trap a big black brittle Star... Using fish pieces ...in my tank. Hides under rock.

What's the most "smelly lol" item I can use as bait to lure him into the trap(diy plastic bottle) or a basket?

Any advice how to catch? Thx

No advice how to catch but if you want smelly leave a frozen raw shrimp out for a few days. Rotten shrimp is plenty smelly
