Can I add more fish?

[rattlesnake attack]

Hello I have a 75 gallon tank with 100lb of live rock. It has been going for 2 years now with a canister filter. My stock list is
2 clownfish
I cardinal fish
2chromis
1 Melanarus wrasse
1 falco hawkfish
1 springers damsel
1 black widow blenny
Can I add any more fish? And if so, how close is it to being overstocked. Please be polite when replying

What are the dimensions of the 75 gallon tank?

Are there a lot of unoccupied holes in the rocks where a new fish can dwell and rest?

It is 48" long, 18" wide, and 20" tall

There are plenty of unoccupied holes where there are no fishes territory

That's a good size space, and it seems like there is room for a few more fishes.

The math also can be helpful. Each fish currently has .66 square feet of floor space, max, not including the space occupied by rocks.

So the math suggests (to me, anyway) that any new addition may increase space competition beyond your current fishes ability to accept new fishes in their tightly packed environment. Proceed with caution and be ready to remove fishes if fighting occurs.
