mantis shrimp tank *needs help*

[the mantis lover]

Hey guys I love mantis shrimp and am starting my first nano reef tank. I've had 1 coral in it for a year now and just added a new one on 11-13-2020. I am looking for small inhabitants for my tank as well as some nice corals. and if possible some I.D. on my mantis shrimp.

tank info

gallons- 3

brand/name- https://dreamfishtanks.com/products..._content=sag_organic&utm_campaign=sag_organic

lighting- I use the built-in lighting. I use the white red light setting in the day and the blue setting at night (the coral that has been in there for a year looks really healthy when fully extended.)

inhabitants-
one male mantis shrimp (size is 1-2 inches) (type-smasher) (I.D. unknown- if possible I would like to know) (area found florida keys)
one starfish (I.D. unknown- if possible I would like to know)
one pencil sea urchin
one mini feather-duster tube worm
one mountain dew toadstool coral (been in the tank for a year)
and one flower tree coral (I think it is a flower tree coral but if it's not pls tell me the I.D.)

pictures-

this is a photo i found online that looks the closest to my starfish

The shrimp is a lime mantis. Max our at around 4 inches. Don’t count on adding many other inverts, and if you add fish they should probably be cheap or really fast.
