Mantis shrimp nano reef *needs help*

[the mantis lover]

*read the about me to know a little more* also, this is my first time here.

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

I didn't mention that I'm looking for a good cleanup crew for algae and detritus. also, I was thinking of adding macro algae what types are good, and I'm looking for something that skeleton shrimp can perch themselves on what coral or plant would be good for that?

I like Halimeda macroalgae, it’s very coastal looking.
