Looks like a type of amohipod.

How big is it? The picture and vid make it look very large.

If it is small, like a relative size to your pinky nail, then it's most likely an amphipod.

 

[Patx]

No, not gammar etc...
Its tiny... more tiny than isopod

3-4 copepode long

 

[Reefkeepers Archive]

It looks like the Anthuroidean Isopods i have in my system

 

[Patx]

In withe light its yellow whit 3 tiny red spot.
Tail or head and claw (not sure)

It looks like the Anthuroidean Isopods i have in my system

Hmm ? Maybe.
Does it have Claw ?

Yes. hold on, let me get the anatomy chart

Yes, they do have small claws used to catch prey like copepods, there are many species in the isopod/amphipod families so @ISpeakForTheSeas may also be able to help, here are some photos I got off the internet that may help

 

[Patx]

Mine is 3mm...max 4mm. (Long)
Could be larvae stage...

This is a Tanaid - they look remarkably similar to Anthuroidean isopods, Ingolfiellidean amphipods, and amphipods from the taxonomic parvorder Corophiidira.

You can tell this is a Tanaid because of two main features:

-The claws (called gnathopods for all of these critters); only Tanaids have the "crab-claw" style gnathopods (i.e. where it has a pincer with two claws instead of a just a hook with one).

-The tail; Tanaid tails are not split, and they are heavily segmented with smaller segments than the rest of the body.

It should be harmless.

Tanaids are generally scavengers eating detritus/algae, but a few eat worms and copepods.
