Don't have any experience with the L# bn but apparently our peppermint bristlenose are as close to L181s as we gonna get... Any ways here's my opinion:
recommended tank size- 2ft for breeding 3ft for breeding and display (bigger is easier to work with IMO)
amount of caves- females like to hide too so can put 2-3
amount of bogwood- Couple nice sized pieces to provide cover (they more nocturnal fish)
filtration- small canister filter like an Eheim 2213, for current a powerhead (internal filter) that does about 500-600L/h and if you like a sponge filter just for some good old O2
circulation- above
substrate- sand is good as it's easy and quick to clean but it does get messy quickly
plants?- I like my anubias on driftwood as you can move em while gravel vacing. Java fern is also good as it's a harder plant to kill lol
temp- keep them at 26-27 and when you want to trigger them you can turn the heater down to 24-25 after waterchanges
ph- neutral 7 to acidic 5.5
Hope that helps and if any one else got somethin to add be my guest
