If you're not convinced that LR
is important, pick up a few good marine books:
The Conscientious Marine Aquariast by Fenner,
The New Marine Aquarium.
Both basically talk about how the addition of LR
in the hobby has allowed species to be kept in captivity that never survived before.
Why? Because the LR
is a huge part of their environment...visually and functionally. It makes them feel secure about surroundings, gives some a place to 'nest', as well as providing ideal bio-filtration.
is expensive...and probably the hardest part of a FOWLR
setup to stomach, cost wise.
