20l AIO stocking

[c_man7]

I should have my false wall and filtration set up in my 20l this weekend and I'll fill her up some time middle of next week, got 20lb of live sand about 20lb of live rock and 5-10lb of dry rock. I'm trying to figure out some decent stocking without overstocking. Coming from a 55 mbuna cichlid tank which needs to be heavily stocked.

I don't want to overstock but don't want to understock with a bare tank.

 

I was thinking of doing a reef with some beginner type corals

 

As far as livestock

I want 2 ocellaris clownfish for sure.

I was thinking maybe also a watchman goby and pistol shrimp pair.

 

Hows this stocking look?

 

Also does a CUC affect bioload, A few snails would be cool

maybe a smaller starfish?
