Lf amphipod eating fish. Mandarin?

[Dendromad]

Need to reduce my amphipod population as the larger ones have taken a liking to eating some of my zoas.

Looking for a small healthy fish, Mandarin dragonnet maybe?
I have a 29 gallon extra long (40" long 14" deep 12" tall.) Bare bottom.

I think a yellow coris wrasse can take care of them

Tank is bare bottom though, don't they sleep in the sand?

Yellow Coris is fine without substrate.

Yes, when I had one in my 90g use to sleep in the sand, I guess is a no no then, I don't really know how they will do in bare bottom

I have same issue - lots of larger amphipods. I have a mandarin but I don't think it eats the bigger amphipods. It pecks away at creatures I cannot see. I have two green spotted puffers and they are voracious; however I find the problem is that pods only come out at night. I see them having a party after lights out when my fish are all asleep. I read that long-nose hawkfish are nocturnal and he does appear to be hunting something but the pod population still seems pretty healthy. I'm not sure if pods are eating my zoas, but my worry is that they are predating copepods which are sustaining my mandarin.
Who knows, maybe I'm reading too much & worrying about nothing.
