Are there any invert dominated reef tanks

[DEE’S reef]

So I was wondering if there are any reef tanks were they are dominated by inverts with very little to no fish.

There are coral only tanks for sure. They bring their own challenges but it is doable with relative ease.

Like I was wondering if there are any tanks that have cool reef safe inverts you usually can’t have because of fish or something

I did have a 20 gallon with a calico crab in it, had it for just over 2 years i think, he finally passed. i still have the tank with 2 banggai cardinal fish. I still have the tank running, has a Sally Lightfoot crab now
