Is there any invert that will help keep my 75g aggressive tank clean

[dangerfish]

So I am planning on getting an aggresive tank and I was wondering if there is any invert that can help keep algae under controll
this is my fish stock i want

One spot fox face
Snowflake Eel
Flame angel
Blue Spotted Puffer (or i might get a porcupine puffer)
Pinkface Wrasse
Humu Picasso Triggerfish

I was thinking of maybe some urchins but im not sure

such as the Longspine Urchin, Black and the Red Tuxedo Urchin

if not red tuxedo maybe the Pincushion Urchin, Hairy

I would think an urchin would work. I have 2 that I just moved to my newer tank that has a bad case of hair algae. They do a great job. You might consider a brittle star.

ok

But don't be surprised if the trigger plucks the spines off of the urchin - I had that happen many years ago, done by a niger trigger.

ok do you think a humu trigger would do that
