I'm starting a new build to house some delicate fish I want to stock it with a pair of orange spotted filefish, pair of blue lined pipefish and a pair of yashi gobys.
I love my 40B. I've got pretty basic fish. Two clowns, fire fish, royal gramma, and a little yellow tang. Two fire shrimp, and am just starting to get a few little corals for it. I know a yellow tang in a 40B is not good, but he his tiny and I plan on upgrading to a 210 in a few months.
I've added the overflow box and returns painted the stand and purchased a current USA compact florescent metal halide light combo lamp to light the tank
