New fish tank

[Tomasz blasz]

How can I improve

 

[RJ Harris]

What are you trying to improve?

 

[Tahoe61]

What type of lighting?
I would add a tad more flow.
I would remove the Anthelia soft coral unless you really want or would like that coral to take over your tank.
How old is the tank?

Welcome. :-)

Over all the tank is a great start.

What direction do you want to take the tank, mixed, sps, lps?

 

[RJ Harris]

I second removing the anthelia. It'll take over every surface.
