Stocking list for 40 gallon FOWLR

So I'm starting a 40 gallon FOWLR and I definitely want to keep things on the pres side. Filtration will be good with lots of LR, a canister filter and a big skimmer.

I plan to keep

- dwarf lionfish
- snowflake eel
- Maroon clownfish
- MAYBE an angler or scorpion
